In addition, the power metering nebulizer of the second embodiment forms a central flow path 127, and communicates with the first flow path 103 so that one side is coupled to the first body 102, and the third flow path is formed as described above. The guide pipe 110 which is connected to the flow path 106 and whose other side is coupled to the said 3rd main body 109 is hold | maintained.

In addition, the circumferential surface of the guide pipe 110, the nut 114 for adjusting the amount of spray liquid is interposed, the piston 111 is interposed to spray the liquid of the second pumping chamber 108, A stopper 116 is interposed between the nut 114 and the piston 111 to adjust the amount of sprayed liquid together with the nut 114, and the stopper centered on the piston 111. On the opposite side of the liquid level control unit 115 to adjust the liquid level and constitute the first pumping chamber 108 ′ is interposed.

Here, the pumping chamber 108 has a first pumping chamber 108 ′ and a second pumping chamber 108 toward the first body 102 and the third body 109 with the piston 111 as the center. It is formed to be distinguished between the inside of the second body 105 and the guide pipe 110.

Of course, the piston 111 has a conventional O-ring is inserted in order to prevent the leakage of liquid, and has a spring 112 used to apply an elastic force to the surface of the second pumping chamber 108 side. have.

In addition, the first pumping chamber 108 may communicate with the second channel 104 of the first body 102.

In the third body 109, a third passage 106 is formed on one surface of the third body 109 so as to communicate with the center passage 127, and the fourth passage communicating with the second pumping chamber 108. A flow path 126 is formed, and the circumferential surface of the valve body 129 is configured to intercept the third flow path 106 described above, and the third flow path 106 and the fourth flow path 126 described above.

Down the lever 120 can be pressed are to be installed to the hinge 119.

Of course, the fifth flow path 132 is formed on the opposing surfaces of the third and fourth flow paths 106 and 126 of the third body 109 so as to communicate with the nozzle means, and connects the nozzle means. It also forms a groove.

Hereinafter, the operating state of the second embodiment will be described with reference to FIG.

In the drawing of (a), in the initial state, that is, the preparation state before injection, when a compressor not shown in the drawing is operated, the high pressure medicine is transferred to the first body 102 through the high pressure flow path 101, Subsequently, the medicine is transferred to the first and second flow paths 103 and 104 of the first body 102.

The medicine transferred to the second flow path 104 is filled in the first pumping chamber 108 ′, and the internal pressure increases continuously, and the pressure generated on one side of the piston 111 is generated. Work force.

At the same time, the chemicals transferred to the first flow path 103 are in the order of the central flow path 127 → the third flow path 106 → the valve chamber 128 → the fourth flow path 126 → the second pumping chamber 108. The pressure is increased, the internal pressure of the second pumping chamber 108 is increased, and a force generated by the pressure is applied to the other surface of the piston 111.

At this time, the force acting on both surfaces of the piston 111 by the pressure of the drug is equivalent, and does not cause any influence on the piston 111.

However, the first body 102 while increasing the volume of the second pumping chamber 108 by a spring 112 interposed between one side of the third body and one surface of the piston 111 and exerts an elastic force. The piston 111 is moved toward).

Thereafter, the piston 111 stops increasing the volume of the second pumping chamber 108 by the liquid level controller 115.

The above state is a spray preparation state, that is, a state of completion of drug filling.

When spraying, when the lever 120 is gripped, the lever 120 rotates about the hinge 119 to push the valve 117 into the third body 109, and the valve body 129. Prevents the surface of the third channel 106 from communicating with the fourth channel 126.

That is, the surface of the valve body 129 completely blocks the flow of the medicine in the third passage.

In this case, the fourth flow path 126 communicates with the fifth flow path 132 through the valve chamber 128, and the chemicals entering the high pressure flow path 101 communicate with the first flow path 103. Since the central flow path 127 is blocked, pressure is applied only to the second flow path 104.

In addition, the pressure of the second pumping chamber 108 is reduced by the injection of the medicine in the order of the second pumping chamber 108 → valve chamber 128 → fifth passage 132 → nozzle means.

Therefore, when the force generated by the pressure difference between the first pumping chamber 108 'and the second pumping chamber 108 is greater than the elasticity of the spring, the piston 111 is the second pumping chamber. Reducing the volume of 108 is to move toward the third body (109).

And, as shown in the diagram of (b), when the piston 111 in contact with the nut 114, the stopper 116 in turn stops the movement, the injection stops.

If the lever 120 is released when the spray preparation state is required again, the elastic force of the spring 122 which pushes the valve 117 out of the third body 109 may be described. The valve 117 comes out and the lever returns to its original state.

Immediately thereafter, as described above, the injection preparation state is reached.

Third Embodiment

As shown in FIG. 5, the third body and the valve means are improved in comparison with the power metering sprayer of the second embodiment.

The third main body 209 of the power metering sprayer of the third embodiment forms a third flow path 206 to communicate with the central flow path 127 on one surface thereof, and a fifth flow path to communicate with the nozzle means on the opposite surface. 232 is formed, intersects with the third and fifth flow paths 206 and 232 and inserts the valve 217, and drills the guide groove 236 for guiding the linear movement of the valve 217. Fourth flow paths 226 ′ and 226 are formed to communicate with the second pumping chamber 108 at both sides about the third flow path 206 in the direction of movement of the valve 217 moving at 236. have.

Of course, a groove is formed in the third body 209 so as to communicate with the fifth flow path 232 and to allow the third body 209 and the nozzle means to be coupled to each other.

In addition, the valve 217 may include a first valve groove (3) in the third and fourth flow paths 206, 226 ', and 226 so that the fourth flow path 226 and the third flow path 206 may pass through in the preparation state for injection. 234 is formed, and the second valve groove 235 is formed on the fifth flow path 232 to communicate with the fifth flow path 232 at the time of injection, and passes through the fourth flow path 226 'at the time of injection. A through flow passage 233 is formed in a direction crossing the circumferential surface so as to pass through the second valve groove 235.

When the valve 217 is installed in the third body 209, the spring 222 that exerts an elastic force under the valve 217 is described above in the third body 209. Interposed between the inner bottom surface of the guide groove 236 and the lower surface of the valve 217 described above.

The medicine transferred to the second flow path 104 is filled in the first pumping chamber 108 ′, and the internal pressure is continuously increased, and the pressure generated on one side of the piston 111 is generated. Work force.

At the same time, the medicine transferred to the first flow path 103 is the central flow path 127 → the third flow path 206 → the first valve groove 234 → the fourth flow path 226 → the second pumping chamber 108. In order to be transferred, the internal pressure of the second pumping chamber 108 is increased, and the force generated by the pressure acts on the other surface of the piston 111.

At this time, the force acting on both surfaces of the piston 111 by the pressure of the drug is equivalent, and does not cause any influence on the piston 111.

However, by the spring 112 interposed between one side of the third body 209 and one surface of the piston 111 and exerts an elastic force, the first pumping chamber 108 increases the volume of the first pumping chamber 108. The piston 111 moves toward the main body 102.

The piston 111 stops movement while being stopped by the liquid level controller 115 and stops increasing the volume of the second pumping chamber 108.

The above state is the completion state of the injection preparation state.

In the case of spraying, when the lever 120 is pressed, the lever 119 is rotated about the hinge 119 to push the valve 217 into the third body 309, and the circumferential surface of the valve 217 is described above. The third passage 206 is prevented from communicating with the fourth passage 226.

At this time, the medicine of the fourth flow path 126 'is communicated to the through flow passage 233 → the second valve groove 235 → the fifth flow passage 232 → the nozzle means is transferred to the high pressure flow path 101 The medicine applies pressure only to the second flow path 104 because the center flow path 127 communicating with the first flow path 103 is blocked.

In addition, the pressure of the second pumping chamber 108 is the second pumping chamber 108 → the fourth passage 226 '→ the through passage 233 → the second valve groove 235 → the fifth passage 232 → the drug is dropped by spraying the nozzle means.

Accordingly, when the force generated by the pressure difference between the first pumping chamber 108 ′ and the second pumping chamber 108 is greater than the elastic force of the spring 112, the piston 111 may be configured as described above. 2 is moved toward the third body 209 while reducing the volume of the pumping chamber (108).

And, as shown in the drawing of (b), when the piston 111 in contact with the nut 114, the stopper 116 in sequence stops the movement, the injection is stopped.

If the above-mentioned lever 120 is released again when the spray preparation state is required, the elastic force of the spring 222 that pushes the valve 217 out of the third body 209 may be used. The valve 217 comes out and the lever 120 returns to its original state.

Immediately thereafter, as described above, the injection preparation state is reached.

Fourth Embodiment

As shown in Fig. 6, the third body and the valve means are improved in comparison with the power metering sprayer of the second embodiment.

The pressure is increased, the internal pressure of the second pumping chamber 108 is increased, and a force generated by the pressure is applied to the other surface of the piston 111.

At this time, the force acting on both surfaces of the piston 111 by the pressure of the drug is equivalent, and does not cause any influence on the piston 111 described above.

However, by the spring 112 interposed between one side of the third body 309 and one surface of the piston 111 and acting elasticity, while increasing the volume of the second pumping chamber 108, the first pump The piston 111 moves toward the main body 102.

The piston 111 is stopped by the liquid level controller 115 to stop the movement and stop the volume increase of the second pumping chamber 108.

The above state is the completion state of the injection preparation state.

When spraying, when the lever 320 is rotated, the valve 317 rotates, and the circumferential surface of the valve 317 blocks the flow of the chemical in the third flow passage 306.

In this case, the medicine of the fourth flow passage 326 is transferred to the nozzle means via the fifth flow passage 332 through the through flow passage 333, and the medicine flowing into the high pressure flow passage 101 passes through the first flow passage ( Since the above-described center flow passage 127 communicating with 103 is blocked, pressure is applied only to the second flow passage 104.

In addition, the pressure of the second pumping chamber 108 is the second pumping chamber 108 → the fourth passage 326 → the through passage 333 → the fifth passage 332 → the nozzle means injecting By falling.

In the drawing of (a), in the initial state, that is, the preparation state before injection, when a compressor not shown in the drawing is operated, the high pressure medicine is transferred to the first body 102 through the high pressure flow path 101, Subsequently, the medicine is transferred to the first and second flow paths 103 and 104 of the first body 102.

The medicine transferred to the second flow path 104 is filled in the first pumping chamber 108 ′, and the internal pressure is continuously increased, and the pressure generated on one side of the piston 111 is generated. Work force.

At the same time, the chemicals transferred to the first flow path 103 include the central flow path 127 → the third flow path 406 → the first valve groove 434 → the fourth flow path 426 → the second pumping chamber 108. In order to be transferred, the internal pressure of the second pumping chamber 108 is increased, and the force generated by the pressure acts on the other surface of the piston 111.

At this time, the force acting on both surfaces of the piston 111 due to the pressure of the chemical agent is equivalent, and does not cause any influence on the piston 111.

However, by the spring 112 interposed between one side of the third body 409 and one surface of the piston 111 and acting elasticity, the first pump while increasing the volume of the second pumping chamber 108 The piston 111 moves toward the main body 102.

The piston 111 stops movement when stopped by the liquid level controller 115 and stops increasing the volume of the second pumping chamber 108.

The above state is the completion state of the injection preparation state.

In the case of spraying, the valve rotation angle adjusting means 438 rotates around the hinge 419 and is pushed to the cable 439 to rotate the valve 417. The circumferential surface of the valve 417 blocks the flow of the medicine of the third passage 406 described above.

At this time, the medicine of the fourth flow path (426 ') is communicated to the through flow passage 433 → the second valve groove 435 → the fifth flow passage 432 → the nozzle means is transferred to the high pressure flow path 101 The medicine applies pressure only to the second flow path 104 because the center flow path 127 communicating with the first flow path 103 is blocked.

In addition, the pressure of the second pumping chamber 108 is the second pumping chamber 108 → the fourth passage 426 '→ the through passage 433 → the second valve groove 435 → the fifth passage 432. → the drug is dropped by spraying the nozzle means.

Accordingly, when the force generated by the pressure difference between the first pumping chamber 108 ′ and the second pumping chamber 108 is greater than the elastic force of the spring 112, the piston 111 may be configured as described above. The pumping chamber 2 moves toward the third body 409 while reducing the volume of the pumping chamber 108.

And, as shown in the drawing of (b), when the piston 111 in contact with the nut 114, the stopper 116 in turn stops, the injection is stopped.

In addition, when the above-mentioned lever 420 is released when the injection preparation state is required, the valve 417 is returned to the initial state by the restoring force of the spring 422, and then, as described above, the injection You are ready.

Here, the positions of the valve groove and the through passage can be changed.

That is, the first valve groove 434 passes through the third passage 406 and the fourth passage 426 'at the time of filling the medicine, and the through passage 433 communicates with the second valve groove 435 at the time of injection. The fourth passage 426 is passed through.

Of course, the power metering nebulizer is to be able to spray the quantitative spray at the time of spraying the medicine, animal fertilizer injection, etc. in the feed of the livestock, not for spraying the pesticide, depending on the contents to be filled.

[effect]

As described above, the present invention can reduce the weight of the nebulizer, reduce the waste of the pesticide, and reduce the waste of the pesticide by making it easy to manufacture the structure and quantitatively spraying the pesticide using power. This can reduce the harm to humans and livestock.

In addition, there is no leakage of pesticides that may occur due to internal problems of the sprayer, there is an advantage that does not harm the human body of the user.
