  The present invention relates to a pollutant ejecting apparatus, and more particularly to a pollutant ejecting apparatus that ejects a polluted liquid.

  Patent document 1 discloses a pollutant jet apparatus. The pollutant jetting device includes a gas generator, a storage container, and a liquid jet nozzle. The gas generator generates gas when an activation signal is input. The liquid injection nozzle is connected to the storage container via a pipe, and sprays the contaminated liquid toward the banknote. The internal space of the storage container is partitioned into a gas filling chamber and a dirty liquid storage bag built-in chamber via a movable disk. The gas filling chamber is filled with gas from a gas generator. In the chamber containing the liquid storage bag, a liquid storage bag containing the liquid is stored. The movable disk can move in the storage container in the axial direction of the container, and has a heat insulating property. The movable disk can be moved toward the chamber containing the pollutant storage bag by the gas pressure generated from the gas generator. The opening end on the side opposite to the gas filling chamber side in the chamber containing the contaminated liquid storage bag is closed with a plug. The plug has a liquid outlet communicating with the pipe. A mouth portion facing the chamber containing the liquid storage bag at the liquid outlet is formed in a sharp edge shape so as to break the liquid storage bag. The part of the plug that is on the inner surface facing the dirty liquid storage bag built-in chamber and corresponding to the outer periphery of the tip part is fixed to the bottom of the dirty liquid storage bag in contact with the part.

  According to Patent Document 1, it is possible to prevent the occurrence of a liquid leak or the occurrence of a situation where the banknote is unintentionally soiled.

  However, the invention disclosed in Patent Document 1 has a problem that it is difficult to reduce the size beyond a certain level. Attempting to downsize beyond that level will result in insufficient jetting of the contaminated liquid.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a pollutant jet apparatus that can be easily downsized.

  The contaminated liquid ejection device of the present invention will be described with reference to the drawings. Note that the use of the reference numerals in the drawing in this column is to help understanding of the contents of the invention, and is not intended to limit the contents of the invention to the illustrated range.

  In order to achieve the above object, according to an aspect of the present invention, the contaminated liquid ejection device includes a storage container 2, a gas generator 4, a pressure resistant container 6, a heat shield plate 10, and a liquid injection nozzle 8. Prepare. The storage container 2 stores the contaminated liquid. The gas generator 4 has a gas discharge port 70, and generates a gas when an activation signal is input, and discharges the gas from the gas discharge port 70. The pressure vessel 6 accommodates the storage container 2. A gas discharge port 70 is connected to the pressure vessel 6. The pressure vessel 6 withstands the pressure of the gas generated by the gas generator 4. The heat shield plate 10 is accommodated in the pressure vessel 6 at a position between the storage container 2 and the gas outlet 70. The liquid injection nozzle 8 communicates with the inside of the pressure resistant container 6 and injects the contaminated liquid onto the injection target when the contaminated liquid is discharged from the storage container 2. When the gas generator 4 generates gas, the storage container 2 is crushed by the pressure of the gas. The pressure vessel 6 has a housing portion 22 and a communication portion 24. The accommodating part 22 accommodates a part of the storage container 2 and the heat shield plate 10. The communication part 24 accommodates the remainder of the storage container 2 and allows the accommodation part 22 and the liquid injection nozzle 8 to communicate with each other. The communication part 24 communicates with the accommodating part 22 through the inner wall opening 80. The inner wall opening 80 is a part of the inner wall of the accommodating portion 22. The storage container 2 includes a storage unit 40 and a pollutant discharge unit 42. The storage unit 40 is housed in the housing unit 22. The storage unit 40 stores the contaminated liquid. The pollutant discharge part 42 protrudes from the storage part 40 and communicates with the storage part 40, and at least the tip part is accommodated in the communication part 24. The pollutant discharge unit 42 discharges the pollutant in the storage unit 40 into the communication unit 24 in response to the storage unit 40 being crushed by the pressure of the gas. The contaminated liquid ejection device further includes a leakage prevention unit 12. The leakage prevention part 12 is disposed between at least one of the inside of the communication part 24 and the outer periphery of the inner wall opening 80 and the storage container 2. When the storage unit 40 is crushed, the leakage prevention unit 12 prevents gas from leaking to the outside of the pressure vessel 6 from between the outer periphery of the pollutant discharge unit 42 and the inner periphery of the communication unit 24.

  When the activation signal is input, the gas generator 4 generates gas and discharges the gas. The storage container 2 is crushed by the gas pressure when the gas generator 4 generates gas. The pollutant discharge unit 42 discharges the pollutant in the storage unit 40 into the communication unit 24 in response to the storage unit 40 being crushed by the pressure of the gas. At this time, the leakage prevention unit 12 prevents gas from leaking from between the outer periphery of the pollutant discharge unit 42 and the inner periphery of the communication unit 24 to the outside of the pressure vessel 6. Compared with the case where it is not provided, the pressure inside the pressure vessel 6 becomes higher. As the pressure increases, the storage container 2 is crushed well. The amount of polluted liquid remaining in the storage container 2 after gas generation is reduced by the amount of being crushed well. Since the remaining amount of the contaminated liquid is reduced, the amount of the contaminated liquid stored in the storage container 2 can be reduced. As a result, the downsizing of the pollutant ejecting device is facilitated.

  In addition, it is desirable that the above-described pollutant discharge portion 42 includes a root portion 50, a constricted portion 52, a tip portion 54, and a foil 56. The root portion 50 communicates directly with the storage portion 40. The constricted part 52 is connected to the base part 50. The constricted part 52 communicates with the storage part 40 via the base part 50. The distal end portion 54 is connected to the constricted portion 52. The distal end portion 54 communicates with the storage portion 40 via the constricted portion 52 and the root portion 50. The distal end portion 54 is provided with a discharge hole 60. The foil 56 is affixed to the distal end portion 54 so as to close the discharge hole 60.

  The contaminated liquid ejection device according to the present invention can be easily downsized.

It is sectional drawing which shows the contaminated liquid ejection apparatus concerning embodiment of this invention. It is an enlarged view which shows the contaminant discharge | release part concerning embodiment of this invention in the state which fractured | ruptured one part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  FIG. 1 is a cross-sectional view showing a contaminated liquid ejection device according to an embodiment of the present invention. FIG. 2 is an enlarged view showing the pollutant discharge part 42 according to the present embodiment in a state where a part thereof is broken.

  With reference to FIG. 1, the structure of the contaminated liquid ejection apparatus according to the present embodiment will be described. The contaminated liquid ejection device according to the present embodiment is installed in a cash storage case of an ATM (Automated Teller Machine) device. As shown in FIG. 1, the contaminated liquid ejection device according to the present embodiment includes a storage container 2, a gas generator 4, a cast pressure container 6, and a liquid injection nozzle 8 connected to the pressure container 6, A heat shield plate 10.

  The storage container 2 stores a contaminated liquid such as colored ink. The storage container 2 in the present embodiment is a bag made of resin such as polyethylene. When the activation signal is input from the control device 14, the gas generator 4 generates gas and discharges the gas from a gas discharge port 70 described later. The pressure vessel 6 accommodates the storage container 2. A gas discharge port 70 (to be described later) of the gas generator 4 is connected to the pressure vessel 6. The pressure vessel 6 according to the present embodiment is made of cast iron. This is strong enough that the pressure vessel 6 can withstand the pressure of the gas generated by the gas generator 4 (as a result, at least gas leakage does not occur until the contaminated liquid is sufficiently pushed out of the storage vessel 2). Because it is necessary to have. In other words, the material of the pressure vessel 6 is not limited to cast iron as long as it can withstand the pressure of the gas generated by the gas generator 4. The liquid injection nozzle 8 is an injection target (in this embodiment, a banknote (not shown) in the cash storage case is the injection target. Of course, the injection target may be an object other than a banknote such as securities). ) Spray the above-mentioned contaminated liquid. The heat shield plate 10 blocks heat. The heat shield plate 10 is provided to protect the storage container 2 from a flame generated when the gas generator 4 generates gas (in this embodiment, this flame is jetted together with the gas from the gas discharge port 70). Because. The heat shield plate 10 can slide in the pressure vessel 6. Naturally, the heat shield plate 10 moves in the direction of crushing the storage container 2 when the gas generator 4 generates gas. For this reason, it is desirable that the heat shield plate 10 be formed of a thin and lightweight material. Specifically, the heat shield plate 10 is preferably made of a material such as mica or flame retardant coated paper.

  The pressure vessel 6 according to the present embodiment is formed in a rectangular tube shape. The internal space of the pressure vessel 6 is partitioned into a gas filling chamber 20, a storage container housing chamber 22, and a communication chamber 24. The gas filling chamber 20 communicates with the storage container housing chamber 22 through the vent hole 26. The storage container housing chamber 22 communicates with the communication chamber 24 via an inner wall opening 80 provided on the inner wall thereof (the inner wall opening 80 is shown in FIG. 2). Further, the storage container housing chamber 22 communicates with the liquid injection nozzle 8 via the communication chamber 24. In the gas filling chamber 20, the tip portion of the gas generator 4 described above (a heat generating portion 30 described later) is accommodated. A part of the storage container 2 (a contaminant discharge part 42 described later) and the heat shield plate 10 are stored in the storage container storage chamber 22. The communication chamber 24 accommodates the remaining part of the storage container 2 (a storage part 40 described later). The heat shield plate 10 is disposed so as to face the surface where the vent hole 26 opens. As a result, the heat shield plate 10 is accommodated in the pressure vessel 6 at a position between the storage container 2 and the gas generator 4 (more specifically, the gas outlet 70).

  The gas generator 4 includes a heat generating unit 30, a lead wire 32, a switch 34, and a power source 36. The heat generating unit 30 includes a gas outlet 70, a gas generating agent (not shown) such as sodium azide, and an electric heating body (not shown). As described above, the heat generating unit 30 is accommodated in the gas filling chamber 20. Since the heat generating part 30 is accommodated in the gas filling chamber 20 and the heat generating part 30 has the gas discharge port 70, the gas discharge port 70 is connected to the pressure resistant container 6. The lead wire 32 is connected to an electric heating body. A switch 34 and a power source 36 are connected to the lead wire 32. The switch 34 is turned on when the control device 14 inputs an activation signal.

  The storage container 2 includes a storage unit 40 and a pollutant discharge unit 42. The storage unit 40 is stored in the storage container storage chamber 22. The pollutant discharge part 42 protrudes from the storage part 40 and communicates with the storage part 40, and at least the tip part is accommodated in the communication chamber 24. The storage unit 40 and the pollutant discharge unit 42 are integrated.

  With reference to FIG. 2, the structure of the pollutant discharge | release part 42 concerning a present Example is demonstrated. The pollutant discharge portion 42 includes a root portion 50, a constricted portion 52, a tip portion 54, and a metal foil 56. The root portion 50 is a portion corresponding to the root of the pollutant discharge portion 42. The base portion 50 is a portion in direct communication with the storage portion 40. The constricted portion 52 is a portion that allows the base portion 50 and the distal end portion 54 to communicate with each other. The O-ring 12 is fitted to the base portion 50. The O-ring 12 is disposed between the inner surface of the communication chamber 24 and the outer surface of the pollutant discharge part 42, and blocks the gas (the gas generated by the gas generator 4) from passing between them. It is a sealing material. The distal end portion 54 is a portion that is connected to the constricted portion 52 and discharges the contaminated liquid. A discharge hole 60 is provided in a portion corresponding to the tip of the tip portion 54. The metal foil 56 is stuck so as to close the discharge hole 60. The strength of the metal foil 56 is low. For this reason, when the storage part 40 is crushed by the pressure of the gas mentioned above, the metal foil 56 is destroyed by the pressure received from the contaminated liquid in the storage part 40. As a result, when the storage unit 40 is crushed, the contaminated liquid is discharged from the discharge hole 60.

  The operation of the contaminated liquid ejection device according to the present embodiment based on the above structure will be described. First, when a known fraud detection device 16 inputs a predetermined signal to the control device 14, the control device 14 inputs a control signal to the switch 34. In response to this, the switch 34 is turned on.

  When the switch 34 is turned on, power flows from the power source 36 to the lead wire 32 to heat the electric heating element. As a result, the gas generating agent causes a chemical reaction and ejects the gas at once. The ejected gas is filled into the gas filling chamber 20 and then ejected to the storage container housing chamber 22 through the vent hole 26. When the gas is ejected into the storage container housing chamber 22, the heat shield plate 10 moves toward the storage container housing chamber 22 due to the pressure of the gas. As the heat shield plate 10 moves, the storage container 2 is compressed toward the communication chamber 24, and at the same time, gas flows from the gap between the outer periphery of the heat shield plate 10 and the inner periphery of the pressure vessel 6 to the storage container 2. The whole storage container 2 is compressed by vigorously flowing in the direction. At this time, leakage of gas from the storage container housing chamber 22 is prevented by the O-ring 12. Since the gas leakage is prevented, the pressure in the storage container housing chamber 22 is increased. Since the air pressure in the storage container housing chamber 22 is increased, the storage container 2 is strongly compressed. Since the storage container 2 is strongly compressed, the volume after compression becomes small. When the storage container 2 is compressed, pressure is applied to the contaminated liquid therein. The metal foil 56 mentioned above is destroyed by the pressure. As the metal foil 56 breaks, the contaminated liquid under pressure is discharged from the discharge hole 60 vigorously. The discharged contaminated liquid is ejected from the liquid ejection nozzle 8 and applied to the banknote.

  As described above, since the storage container 2 is strongly compressed and becomes small in the contaminated liquid ejection device according to this embodiment, most of the contaminated liquid can be ejected from the liquid ejection nozzle 8. Since most of the turbid liquid is ejected from the liquid jet nozzle 8, it is not necessary to store extra turbid liquid in the storage container 2. Since it is not necessary, it is easy to reduce the size of the pollutant ejection device. Moreover, the ratio of what is used with respect to the stored contaminated liquid becomes high.

  The embodiments disclosed herein are illustrative in all respects. The scope of the present invention is not limited based on the above-described embodiment, and various design changes may be made without departing from the spirit of the present invention.

  For example, instead of the O-ring 12, other sealing materials may be used. A leakage prevention member that prevents gas from leaking out of the storage container housing chamber 22 other than the sealing material may be used. In this case, the leakage preventing member may be disposed not on the constricted portion 52 but on the outer periphery of the inner wall opening 80. Further, the leakage preventing member and the O-ring 12 may be used in combination.

  Moreover, the structure of the pollutant discharge | release part 42 is not restricted to what is shown in FIG. For example, when the storage part 40 is crushed by the pressure of gas, the structure which the center part among the constriction parts 52 and the front-end | tip parts 54 may fracture | rupture may be sufficient. The pollutant discharge part 42 may have a valve. Also in these cases, in response to the storage unit 40 being crushed by the gas pressure, a contaminated liquid such as colored ink is released.
