Description

  The present invention relates to an odor generation alarm device that notifies an abnormal situation such as a fire by generating an odor.

  Prior art fire alarm devices detect heat, smoke, gas and flame light generated by fire, and judge them by themselves or in combination to prevent false alarms etc. Composed. The signal detected in this way was given to a fire extinguisher, and a bell was sounded and a sprinkler was operated. However, such a fire alarm device is difficult for people with hearing impairments to notice, and the start of evacuation may be delayed.

  There has been disclosed an alarm device that solves the above-described problem that it is impossible to notify the occurrence of a fire to people with hearing impairments when a fire occurs. In this alarm device, an emergency situation such as a fire is notified by releasing an odor when a fire occurs (see, for example, Patent Document 1).

JP 2004-326326 A

  In the above-described conventional technology, devices that generate odors by various methods are disclosed. However, since each device has a discharge means constituted by mechanical elements, it can be reliably discharged in an emergency due to corrosion or the like. It is not a simple configuration. Moreover, it is not the structure which can diffuse an odor efficiently, and there exists a problem that it takes time until the person who should warn recognizes an odor.

  Accordingly, an object of the present invention is to provide an odor detection alarm device capable of ensuring the reliability of the discharge operation and the odor diffusibility.

The present invention is a casing that fills the odor liquid and forms a storage space capable of storing a spray can that can be switched between a release state that releases the odor liquid and a discharge stop state;
Switching means for switching from the discharge stop state to the discharge state by displacing the spray can stored in the storage space of the casing with respect to the casing;
When abnormal information indicating that an abnormal situation has occurred is given from the detecting means for detecting the occurrence of an abnormal situation, the switching means is displaced with respect to the casing by the switching means, and the operation is switched from the release stop state to the release state. And an odor generation alarm device including a control means.

In the present invention, the switching means further includes an operating portion made of a material that expands and contracts when energized.
The said control means displaces a spray can by energizing with respect to an action | operation part, It is characterized by the above-mentioned.

  Further, the present invention is characterized in that the switching means generates gas by igniting explosive and displaces the spray can by the pressure of the gas.

  Furthermore, the present invention is characterized in that it further includes buffer means for buffering an impact generated when the spray can is displaced in the storage space by the switching means.

  According to the present invention, when the abnormality information indicating that an abnormal situation has occurred is given from the detecting means for detecting the occurrence of an abnormal situation, the switching means is switched by the control means. The switching means can displace the spray can with respect to the casing and switch to the discharge state to discharge the odor liquid filled in the spray can. Therefore, when an abnormal situation such as a fire occurs, the odor liquid filled in the spray can can be released. By using the spray can in this way, the odor liquid can be diffused over a wider range than when the odor liquid such as a tube-shaped container is filled. Moreover, since the switching means can displace the spray can with respect to the casing and can maintain the release state, the spray can can continuously release the odor liquid. Therefore, a desired amount of odor liquid can be released. As a result, the odor liquid can be reliably diffused in a short time to the person who should evacuate to the abnormal situation, and the abnormal situation can be quickly recognized. Therefore, even a person with hearing impairment can recognize that an abnormal situation such as a fire has occurred by odor gas, and can quickly move to an evacuation action.

  According to the invention, the switching means further includes an operating portion made of a material that expands and contracts when energized. The control means displaces the spray can by energizing the operating part. The spray can can be displaced with a simple configuration of energizing the operating portion made of such a material. Therefore, the switching means can be reduced in size and weight.

  According to the present invention, the switching means generates gas by igniting the explosive and displaces the spray can by the pressure of the gas. By igniting the explosive in this way, gas can be generated in an extremely short time, so that the responsiveness to abnormal information can be enhanced. Further, by using explosives, it is possible to prevent the switching operation from being caused by corrosion or the like, and to reliably perform the switching operation, rather than configuring the switching means with mechanical elements.

  Further, according to the present invention, since the shock generated when the spray can is displaced in the storage space by the switching means is buffered by the buffer means, the spray can can be prevented from being damaged during the switching operation. As a result, even when the spray can is suddenly displaced using the explosive as described above, the spray can can be prevented from being damaged, and the switching means can surely switch the spray can to the discharge state.

  Hereinafter, a plurality of embodiments for carrying out the present invention will be described with reference to the drawings. Portions corresponding to the matters described in the preceding forms in each embodiment are denoted by the same reference numerals, and overlapping description may be omitted. When only a part of the configuration is described, the other parts of the configuration are the same as those described in the preceding section. Not only the combination of the parts specifically described in each embodiment, but also the embodiments can be partially combined as long as the combination does not hinder.

  FIG. 1 is a cross-sectional perspective view schematically showing an odor generation alarm device 1 according to a first embodiment of the present invention. FIG. 2 is a perspective view showing the odor generation alarm device 1 in a simplified manner. FIG. 3 is a block diagram showing an electrical configuration of the alarm system 2 including the odor generation alarm device 1. When the alarm system 2 detects an abnormal situation such as a fire, the alarm system 2 operates a fire extinguishing device 3 such as a sprinkler. In the case of an abnormal situation, the fire extinguishing device 3 notifies the abnormal situation by the odor generation warning device 1 that functions as an alarm means. Referring to FIG. 3, the alarm system 2 includes a sensor 4, a fire extinguishing device 3, an odor generation alarm device 1, and an alarm bell 5 and an alarm light 6 that function as other alarm means.

  The sensor 4 is a detection means, and detects the occurrence of an abnormal situation. When detecting the occurrence of the abnormal situation, the sensor 4 gives abnormal information indicating that the abnormal situation has occurred to the fire extinguisher 3. The sensor 4 is configured to detect, for example, heat, smoke, gas, and flame light generated by a fire, and to determine the fire alone or in combination to prevent false alarms and the like. . When the sensor 4 determines that the fire is based on the detected information, the sensor 4 gives abnormal information to the fire extinguisher 3.

  The fire extinguishing device 3 is electrically connected to the sensor 4 and starts a fire extinguishing operation when abnormality information is given from the sensor 4. The fire extinguisher 3 operates a fire extinguishing means such as a sprinkler and a smoke exhaust device. The fire extinguisher 3 controls the alarm means 1, 5, and 6 to issue an alarm when the abnormality information is given from the sensor 4. The alarm bell 5, the alarm lamp 6, and the odor generation alarm device 1 are alarm means, and are electrically connected to the fire extinguishing device 3, respectively, and issue an alarm when abnormal information is given from the fire extinguishing device 3. The alarm bell 5 generates an alarm sound, the alarm lamp 6 emits light, and the odor generation alarm device 1 generates odor.

  Next, the electrical configuration of the odor generation alarm device 1 will be described in detail with reference to FIG. The odor generation alarm device 1 includes a circuit unit 7, a power supply unit 8, an initiator 9, a drive unit 10, and a spray can 11. In FIG. 3, for easy understanding, the drive unit 10 and the spray can 11 that are not electrically connected are virtually illustrated. The circuit unit 7 has a function as control means, and operates the initiator 9 when abnormal information is given from the sensor 4. The circuit unit 7 is electrically connected to the sensor 4 and supplies current to the initiator 9 when abnormality information is given from the sensor 4. The initiator 9 generates heat by an electric current, and an igniting agent (explosive) included in the initiator 9 is ignited. When the ignition agent ignites, the gas generating agent chemically reacts with the heat of the explosive to generate gas. The drive unit 10 is operated by the pressure of the gas, and the spray can 11 is displaced. Thereby, the odor liquid filled in the spray can 11 is released. Therefore, the initiator 9 and the drive unit 10 have a function as switching means, and are switched from the discharge stop state to the discharge state by displacing the spray can 11 with respect to the casing 12.

  FIG. 4 is a cross-sectional view showing the odor generation alarm device 1. With reference to FIG. 1 and FIG. 2 together, the mechanical configuration of the odor generation alarm device 1 will be described. The odor generation alarm device 1 further includes a casing 12 and a power switch 13. Such an odor generation alarm device 1 is suitably used when it is arranged on the floor or hung on a wall. The casing 12 is formed of a cylindrical member extending along a predetermined axis, and a storage space in which the spray can 11 can be stored and an arrangement space in which each part can be stored are formed. The arrangement space is formed adjacent to the storage space, and stores the power supply unit 8, the drive unit 10, the initiator 9, and the circuit unit 7. In addition, a power switch 13 is provided on the outer peripheral portion of the casing 12 so that the state of electricity supply from the power supply unit 8 to the circuit unit 7 can be switched.

  The circuit unit 7 includes a terminal block 14, a circuit board 15, a capacitor 16 and a connector 17. The terminal block 14 is a part that is electrically connected to the sensor 4 via a cable or the like. As shown in FIG. 2, the terminal block 14 is disposed, for example, at one end portion of the casing 12 in the axial direction and is exposed to the outside. The terminal block 14 is electrically connected to the circuit board 15. Therefore, the abnormality information from the sensor 4 is given to the circuit board 15 via the terminal block 14.

  The power switch 13 is electrically connected to the circuit unit 7 and is configured to be able to switch the voltage state from the power source unit 8. The power supply unit 8 is realized by, for example, the battery 8, is detachably provided on the odor generation alarm device 1, and is configured to be able to supply power to the circuit board 15 by being attached to the odor generation alarm device 1. The battery 8 is realized by a primary battery such as a dry battery 8 or a secondary battery such as a rechargeable battery.

  The circuit board 15 charges the capacitor 16 in advance with energy necessary for igniting the gunpowder of the initiator 9 with the power supplied from the battery 8. The circuit board 15 is electrically connected to the capacitor 16 and the connector 17. The circuit board 15 gives the connector 17 the current discharged to the capacitor 16 based on the abnormality information given from the terminal block 14. The connector 17 is electrically connected to the initiator 9 and operates the initiator 9 by applying a current from the capacitor 16.

  As described above, the initiator 9 is operated by the current supplied from the capacitor 16 by the circuit unit 7 and generates gas. The generated gas is discharged into the sealed space 18 formed by the casing 12, the initiator 9, and the drive unit 10, and the pressure in the sealed space 18 is increased. Such a sealed space 18 is kept airtight by O-rings.

  The drive unit 10 operates with the gas generated by the initiator 9 as described above. The drive unit 10 includes a piston 19 and a buffer means 20. The piston 19 forms a sealed space 18 and can be displaced over the discharge stop position and the discharge position along the axial direction of the casing 12. The buffer means 20 buffers an impact generated when the spray can 11 is displaced with respect to the casing 12. The buffer means 20 is realized by the spring member 20 in the present embodiment. The spring member 20 applies a spring force so that the piston 19 is directed in one axial direction.

  The spray can 11 is detachably provided in a storage space formed on the other axial side of the casing 12. The spray can 11 is filled with a compressed gas such as odor liquid and compressed air, and discharges the odor liquid in the form of fine particles by discharging the odor liquid pressurized by the compressed gas from the narrow hole of the nozzle head 21. it can. The spray can 11 is configured to be switchable between a release state for releasing the odor liquid and a release stop state. The spray can 11 is realized by a compressed gas cylinder, for example. The spray can 11 has a substantially cylindrical shape, and is provided in the storage space so that its axis is substantially coaxial with the axis of the casing 12. The top of the spray can 11 is provided on the other axial side of the casing 12. The spray can 11 includes a nozzle head 21 that discharges the odor liquid, and a pressure vessel 22 that is filled with the odor liquid and the compressed gas. At the top of the spray can 11, a nozzle head 21 that discharges the odor liquid filled in the spray can 11 is provided. The spray can 11 releases the odor liquid by being relatively displaced in the direction in which the nozzle head 21 and the pressure vessel 22 approach each other. The pressure vessel 22 is provided so as to be close to the nozzle head 21 in the storage space. When the spray can 11 is stored in the storage space and the spray can 11 is in a discharge stop state, the end wall portion 12a on the other side in the axial direction of the casing 12 forming the storage space is the nozzle head of the pressure container 22. 21 is separated from the end face 22 a facing the side 21. The nozzle head 21 is provided fixed to the casing 12 in the storage space in a state where the spray can 11 is stored in the storage space.

  In the casing 12, a discharge hole 23 is formed along a radial direction that is a direction in which the odor liquid is discharged from the discharge port 21 a of the nozzle head 21. The discharge hole 23 is formed in a tapered shape whose diameter is increased outward in the radial direction. Thus, by forming the discharge hole 23 in a tapered shape, the fine odor liquid discharged from the nozzle head 21 can be efficiently diffused without adhering to the inner peripheral surface facing the discharge hole 23. . The casing 12 and the drive unit 10 are made of a material that does not undesirably deform due to the gas pressure generated by the initiator 9, and for example, materials such as brass, stainless steel, and synthetic resin are used.

  FIG. 5 is a cross-sectional view showing the odor generation alarm device 1 when the spray can 11 is in the discharge state. In a natural state where the pressure by the initiator 9 is not applied, the piston 19 is positioned at a discharge stop position (see FIG. 4) closer to the axial direction by the spring force of the spring member 20. As described above, when the pressure in the sealed space 18 is increased by the gas generated by the initiator 9, the gas pressure acts on the piston 19, and against the spring force of the spring member 20, from the discharge stop position toward the other in the axial direction. Displacement to the discharge position (see FIG. 5).

  The displacement of the nozzle head 21 is regulated by the casing 12, and the pressure vessel 22 extends from a can stop position (see FIG. 4) where the discharge state is stopped with respect to the casing 12 to a can discharge position (see FIG. 5) where the pressure vessel 22 is released. Displaceable. As shown in FIG. 4, when the pressure vessel 22 is in the can discharge stop position and the piston 19 is in the discharge stop position, the bottom of the spray can 11 is in a state where the surface of the other side in the axial direction of the piston 19 is in contact. is there. As shown in FIG. 5, when the piston 19 is displaced and is in the discharge position, the piston 19 presses the bottom of the pressure vessel 22 toward the other side in the axial direction, and from the can discharge stop position toward the other side in the axial direction. Displace to the can release position. As a result, the end wall portion 12a on the other side in the axial direction of the casing 12 contacts the end surface 22a of the pressure vessel 22 facing the nozzle head 21. Since the nozzle head 21 is fixed by the casing 12, the odor liquid is discharged from the nozzle head 21 when the pressure vessel 22 is displaced in the direction closer to the can discharge position with respect to the nozzle head 21. Since the gas generated by the initiator 9 is in the sealed space 18, the pressure by the gas displaces the piston 19 to the discharge position (see FIG. 5) and maintains this state. Accordingly, since the pressure vessel 22 is also kept at the can discharge position, the odor liquid is continuously discharged from the nozzle head 21.

  The odor liquid medicine of the odor liquid filled in the spray can 11 as described above is selected on the assumption that it is an abnormal situation and promotes evacuation behavior. As an odor drug, for example, a drug having a mint odor and wasabi odor is used as a base. As the gas filled in the spray can 11, a gas or air that does not burn even in the flame is selected.

  Further, the spray can 11 may be configured to generate an odor gas through a chemical change of the odor drug and to inject the odor substance with the driving force. The gas pressure generated by the chemical reaction of the odor drug enables the gasification of the odor liquid. In this way, the odor liquid can be diffused over a wide range in a short time by diffusing the odor liquid in a mist form.

  The amount of odor liquid to be filled and the amount of compressed gas are selected based on the volume of the installation space in which the odor generation alarm device 1 is installed. By setting the spray can 11 in the released state, an amount is selected so that the odor liquid to be filled is sufficiently diffused in the installation space and a person in the installation space notices the odor. .

  As described above, in the odor generation alarm device 1 of the present embodiment, when the abnormality information indicating that an abnormal situation has occurred is given from the sensor 4 that detects the occurrence of the abnormal situation, the circuit unit 7 causes the initiator 9 to Is operated. The initiator 9 displaces the piston 19 of the drive unit 10 to displace the spray can 11 with respect to the casing 12. As a result, the spray can 11 is switched to the discharge state, and the odor liquid filled in the spray can 11 can be discharged in the form of fine particles. Therefore, when an abnormal situation such as a fire occurs, the odor liquid filled in the spray can 11 can be released. By using the spray can 11 in this way, the odor liquid can be made into fine particles by the compressed gas and diffused over a wide range as compared with the case where the odor liquid such as a tube-shaped container is filled. it can. Moreover, since the drive part 10 displaces the spray can 11 with respect to the casing 12 and makes it a discharge | release state, the spray can 11 can discharge | release odor liquid continuously. Therefore, a desired amount of odor liquid can be released. As a result, the odor liquid can be reliably diffused in a short time to the person who should evacuate to the abnormal situation, and the abnormal situation can be quickly recognized. Therefore, for example, even a person with hearing impairment and an animal such as a pet can recognize that an abnormal situation such as a fire has occurred by using odor gas and can quickly move to an evacuation action. Further, the odor generation alarm device 1 can be widely used as an alarm device not only for a fire but also for all dangers and abnormal situations by employing a sensor corresponding to the detection target of the sensor 4.

  In the present embodiment, the switching means for displacing the spray can 11 with respect to the casing 12 to switch from the discharge stop state to the discharge state is realized including the initiator 9. The initiator 9 generates gas by igniting explosives, and displaces the spray can 11 by the pressure of the gas. By igniting the explosive in this way, gas can be generated in an extremely short time, so that the responsiveness to abnormal information can be enhanced. Further, by using explosives, it is possible to prevent the switching operation from being caused by corrosion or the like, and to reliably perform the switching operation, rather than configuring the switching means with mechanical elements.

  In the case where the switching means is configured to include the initiator 9, it is preferable that the explosive is ignited when the internal structure of the portion of the initiator 9 is exposed by unauthorized means. As a result, it is possible to prevent the explosive contained in the initiator 9 from being taken out by unauthorized means. As a result, the explosive contained in the initiator 9 can be prevented from being used for other purposes, and safety can be improved. The detection of opening / closing of the casing 12 by an unauthorized means is realized by, for example, a limit switch.

  Furthermore, in this embodiment, since the impact generated when the spray can 11 is displaced with respect to the casing 12 is buffered by the spring member 20 functioning as the buffer means 20, the spray can 11 is damaged during the switching operation. Can be prevented. As a result, even when the spray can 11 is suddenly displaced using the explosive as described above, the spray can 11 is prevented from being damaged, and the initiator 9 and the drive unit 10 surely switch the spray can 11 to the discharge state. be able to.

  In the present embodiment, it is possible to ensure safety during normal times by using the spray can 11 that does not explode due to heat. Furthermore, long-term storability can be ensured by filling the spray can 11 with the odor liquid.

  Moreover, in this Embodiment, the casing 12 and spray can are discharged | emitted so that the one end part by the side of the nozzle head 21 of the spray can 11 may be fixed with the casing 12, and the other side may be pressed to the nozzle head 21 side. 11 is configured. As described above, the displacement of the pressure vessel 22 from the can discharge position toward the nozzle head 21 is restricted by the casing 12, so that the load acting on the nozzle head 21 during discharge can be reduced. Therefore, it is possible to prevent the nozzle head 21 from being damaged by the pressure of the initiator 9, and the odor liquid can be reliably discharged in an abnormal situation. Further, since the nozzle head 21 is fixed by the casing 12, the nozzle head 21 is not undesirably displaced with respect to the casing 12, so that the odor liquid can be discharged in a desired discharge direction.

  In the above-described embodiment, the odor generation alarm device 1 is realized by separate devices for the alarm bell 5 and the alarm lamp 6, but the present invention is not limited to this, and the odor generation alarm device 1 is used as the alarm bell 5. It may be realized by incorporating sound generating means such as a functioning buzzer and light emitting means functioning as the warning light 6. Thus, by incorporating the notification means functioning as the other alarm means 5 and 6 into the odor generation alarm device 1, the odor generation alarm device 1 visually recognizes the odor generation alarm device 1 when the odor is felt. It can be confirmed whether or not the odor is released. Thus, even a person who has a hearing impairment can recognize the state in which the alarm is being issued reliably by visually recognizing the odor generation alarm device 1 after feeling the odor.

  In the above-described embodiment, the alarm means includes the odor generation alarm device 1, the alarm bell 5, and the alarm lamp 6. However, the present invention is not limited to this, and at least the odor generation alarm device 1 is included. It may be combined with other alarm means as appropriate.

  In the above-described embodiment, the sensor 4 and the odor generation alarm device 1 are electrically connected via a fire extinguishing device 3 by wire, but the abnormality information is not limited to wire but can be received wirelessly. May be.

  The odor generation alarm device 1 may be integrated with a fire extinguishing device 3 using a colorless and odorless gas, for example, carbon dioxide. The odor generation alarm device 1 is controlled so as to generate odor in the area where carbon dioxide is injected at the same time as it injects carbon dioxide. As a result, carbon dioxide has a danger of suffocation, so that it is possible to prevent the odor from entering a region filled with carbon dioxide.

  Moreover, although the case where it was electrically connected to the fire extinguishing apparatus 3 was shown in above-mentioned embodiment, it is not restricted to such a form, The other alarm means 5, 6 electrically connected to the fire extinguishing apparatus 3 The odor generation alarm device 1 may be electrically connected to provide abnormality information. Further, the odor generation alarm device 1 may be configured to detect a sound emitted by the alarm bell 5 when the alarm bell 5 is activated and generate an odor by using the sound as abnormal information.

  The fine odor liquid and gas discharged from the spray can 11 may be colorless or colored. When the liquid or gas discharged from the spray can 11 is colored, it is determined whether or not the odor is emitted by the odor generation alarm device 1 by visually checking the odor generation alarm device 1 when the odor is felt. Can be confirmed. Thus, even a person who has a hearing impairment can recognize the state in which the alarm is being issued reliably by visually recognizing the odor generation alarm device 1 after feeling the odor.

  Further, in the above-described embodiment, the buffer means 20 is realized by the spring member 20, but is not limited to such a configuration. For example, an orifice is provided in the piston 19 that constitutes the drive unit 10, and the initiator 9 May be configured to absorb the impact by depleting fluid frictional energy as the gas generated by the gas passes through the orifice. The buffer means 20 may be realized by an attenuator such as a damper. Further, the buffering means 20 is not limited to the structure provided integrally with the switching means, and the spray can 11 may be configured so as to reduce the impact force generated by the displacement. Therefore, for example, the spring member may be provided close to the pressure vessel 22 of the spray can 11 so that the spring force is applied in the direction opposite to the direction in which the spray can 11 is displaced from the discharge stop state to the discharge state.

  Alternatively, the odor liquid may be manually released from the spray can 11 while the spray can 11 is mounted on the casing 12. In this way, by manually configuring the spray can 11 so that the odor liquid can be discharged, the operator can confirm the odor of the odor liquid in advance. Therefore, it is possible to recognize in advance the odor emitted from the odor generation alarm device 1 in an abnormal situation.

  Further, when the spray can 11 is at the can discharge position, the casing 12 may be configured so that the spray can 11 can be displaced manually so that the spray can 11 is in a discharge stop state. With this configuration, when the sensor 4 malfunctions or when the operation is regularly checked, the odor liquid can be discharged by stopping the odor liquid by a desired amount, so that the odor liquid is wasted. Can be prevented from being released.

  The switching means is realized by the drive unit 10 and the initiator 9, but is not limited to such a configuration, and the spray can 11 may be displaced by a drive means such as a motor and a solenoid. The switching means may use a pressure generated by vaporizing a liquid by a chemical reaction or heat, and may be configured to displace the spray can 11 using a spring force.

  Moreover, you may provide diffusion means, such as a propeller, integrally or separately so that the odor liquid discharge | released from the spray can 11 may spread | diffuse further in a short time.

  Moreover, although the discharge hole 23 is formed in the casing 12, you may comprise the casing 12 so that the discharge port 21a of the nozzle head 21 may be directly exposed outside without providing such a discharge hole 23. . Thus, by exposing the discharge port 21a of the nozzle head 21 to the outside, it is possible to reduce the obstacles that hinder the diffusion of the odor liquid, and to further improve the diffusibility.

  In addition, a substance that changes its color when the odor liquid adheres to the wall portion facing the discharge hole 23 of the casing 12 may be applied in advance. By applying such a substance, a third person can easily visually confirm whether or not the odor liquid has been released from the spray can 11. Such a substance is realized by water-soluble ink, for example.

  Next, the odor generation alarm device 1A according to the second embodiment of the present invention will be described. FIG. 6 is a sectional view showing an odor generation alarm device 1A according to the second embodiment of the present invention. FIG. 7 is a block diagram showing an electrical configuration of the alarm system 2 including the odor generation alarm device 1A. The odor generation alarm device 1A of the present embodiment is characterized in that the switching means includes a tension member 24 and a material that contracts when energized, and in this embodiment, an operating portion 25 made of a shape memory alloy.

  As shown in FIGS. 6 and 7, the odor generation alarm device 1 </ b> A includes an operating unit 25 and a tension member 24 that function as switching means. The circuit unit 7 operates the operating unit 25 when the abnormality information is given from the sensor 4. The circuit unit 7 is electrically connected to the operating unit 25 and energizes the operating unit 25 when abnormality information is given from the sensor 4. The operating portion 25 is made of a shape memory alloy in the present embodiment and contracts when energized. The tension member 24 applies a constant load to the operating unit 25. In the present embodiment, the operating portion 25 contracts in the axial direction when energized, and extends in the axial direction when energization is stopped. Therefore, the actuating unit 25 is configured to repeat the bi-directional operation in the axial direction depending on the presence / absence of energization.

  As shown in FIG. 6, the operating portion 25 is provided along the outer periphery of the spray can 11 so as to be substantially U-shaped when viewed from the outside in the radial direction of the spray can 11. The actuating portion 25 has a substantially U-shaped bottom portion 26 located at the bottom of the spray can 11. Accordingly, the operating portion 25 is provided with two end portions 25a and 25b at two different positions 27a and 27b in the vicinity of the radially outer side of the top portion of the spray can 11. One end portion 25a of the operating portion 25 is fixedly provided at one of the two different positions 27a and 27b. The other end portion 25b of the operating portion 25 is provided by being connected to a tension member 24 provided at the other position 27b of the two different positions 27a and 27b. The operating portion 25 has one end portion 27 a electrically connected to the circuit portion 7, and the other end portion 27 b electrically connected to the circuit portion 7 via the tension member 24. Therefore, when the operating portion 25 is energized and its length is reduced, the both end portions 25a and 25b are fixed, so that the distance from the both end portions 25a and 25b to the substantially U-shaped bottom portion 26 is increased. Get smaller. Moreover, it is preferable to comprise the action | operation part 25 so that it may have insulation. In the present embodiment, the operating portion 25 is used by being covered with an insulating material. Accordingly, when the operating unit 25 is energized, even if the operating unit 25 abuts on another member having conductivity, for example, the pressure vessel 22, it is possible to prevent an undesired current from flowing into the pressure vessel 22.

  The tension member 24 is connected to the other end portion 25b of the linear wire actuating portion 25, and is configured to apply a predetermined constant load in the tension direction. Moreover, the tension member 24 has a function as a play allowance, and can improve workability when the operation unit 25 is attached. In the present embodiment, the tension member 24 is realized by a coil spring and is made of a conductive material. In the present embodiment, the tension member 24 is used by being covered with an insulating material. Thus, when the operating unit 25 is energized, even if the tension member 24 contacts another member having conductivity, for example, the pressure vessel 22, it is possible to prevent an undesired current from flowing into the pressure vessel 22.

  FIG. 8 is a cross-sectional view showing the odor generation alarm device 1A when the spray can 11 is in a discharge state. The spray can 11 is located at a can discharge stop position (see FIG. 6) closer to one side in the axial direction when the operation unit 25 is not energized. As described above, when the operating unit 25 is energized from the state shown in FIG. 6, the length of the operating unit 25 is reduced, so that the pressure container 22 of the spray can 11 is moved from the can discharge stop position toward the other in the axial direction. Displacement to the discharge position (see FIG. 8). Accordingly, since the nozzle head 21 is fixed by the casing 12, the odor liquid is discharged from the nozzle head 21 when the pressure vessel 22 is displaced in the direction approaching the can discharge position with respect to the nozzle head 21. Since the operating unit 25 is kept in a state where the length dimension is small while energized, the state in which the pressure vessel 22 is in the can discharge position is maintained, and the odor liquid is continuously discharged from the nozzle head 21. Is done.

  The material that contracts when energized is used for such an operating unit 25 is selected based on at least the following three selection factors. The first selection factor is that the amount of expansion / contraction when energized is a distance from the can position where the odor liquid is discharged to the can position where the discharge is stopped, for example, 3 mm or more. This is because the odor liquid cannot be discharged from the spray can 11 when the operating portion 25 is energized when the amount is less than the expansion / contraction amount. The second selection factor needs to be able to discharge below a predetermined current. This is because the operating unit 25 can be operated even when the current supplied by the power supply unit 8 is small. The third selection factor is to have a predetermined tensile force. This is because, when the operation unit 25 is energized, a force capable of displacing the pressure vessel 22 from a can discharge stop position where the nozzle head 21 is in a natural state to a dischargeable position is necessary. Such a tensile force is 15 N (1.5 kgf) or more, for example. Based on such a selection factor, the diameter, the number, and the material of the operating portion 25 are appropriately selected. The operating portion 25 has, for example, a wire diameter of 200 μm, an operating current of 1 A, a maximum load load of 12 N (1.2 kgf), and a practical operating strain of 5%, the composition of which is Ti 49.0 to 51.0 at%, Cu This is realized by using two or more NiTiCu shape memory alloy wires containing 5.0 to 12.0 at% and the balance being Ni.

  As described above, the present embodiment further includes a working part 25 made of a material that contracts when the switching means is energized, and in the present embodiment, a shape memory alloy. The circuit unit 7 is heated by energizing the operating unit 25, and the operating unit 25 is deformed by the heating to displace the spray can 11. The spray can 11 can be displaced with a simple configuration in which the operation unit 25 is energized. Therefore, the switching means can be reduced in size and weight.

  When the switching means is configured by the initiator 9 as in the above-described embodiment, the initiator 9 needs to be replaced every time it operates, but the material that contracts when the switching means is energized as in this embodiment. By using, it can be used repeatedly, not limited to once.

  The circuit unit 7 may be configured to include a timer. Accordingly, when the abnormality information is given from the sensor 4, the circuit unit 7 can operate the operation unit 25 for a predetermined time based on a timer, for example, 30 seconds. By energizing the actuating unit 25 for a long time, the temperature of the actuating unit 25 or the battery 8 is undesirably increased and other members can be prevented from being damaged by the heat, and are operated for a predetermined time. Thus, a necessary amount of odor liquid can be released from the spray can 11.

In the present embodiment, the operating unit 25 is disposed so as to press the bottom of the pressure vessel 22 toward the nozzle head 21. However, the present invention is not limited to this configuration, and the nozzle head 21 is moved to the pressure vessel 22. You may comprise so that it may press with respect to.
In the present embodiment, the material that contracts when energized is realized by a shape memory alloy, but is not limited to a shape memory alloy, and may be another material that has a function of contracting when energized. The material is not limited to a material that contracts when energized, and may be another material that has a function of expanding and contracting when energized.

  Moreover, when the action | operation part 25 is implement | achieved by a linear wire, the part which presses the spray can 11 of the action | operation part 25 (this Embodiment) so that the action | operation part 25 may not leave | separate from the part which presses the spray can 11 undesirably. Then, you may comprise the bottom part 26) of the spray can 11 so that it may be fixed to the spray can 11 using a fixing means. The fixing means can be realized by, for example, a recess into which the operating unit 25 is fitted, a C-shaped hook unit that hooks the operating unit 25, or the like. Accordingly, when the operation unit 25 is energized, the operation unit 25 can reliably press the spray can 11.

Thus, when the odor generation alarm device 1 detects an illegally used game machine, it can emit an odor to an operator who operates the game machine.

  In addition, the security area is set so that money can be prevented from being stolen from the counter, safe, and cash register at banks and retail stores. For example, the odor generation alarm device 1 is provided for each counter, safe, and cash register. It is done. Thus, when the odor generation alarm device 1 detects the theft of money and the possibility of theft, the odor generation warning device 1 can emit an odor to the theft. The warning area is set, for example, in the driver's seat of the car or the rear seat of the taxi, and the odor generation alarm device 1 is provided for preventing theft of the car and preventing theft in the taxi.

  Moreover, the control part 30 may control so that generation | occurrence | production of the odor by the odor generation alarm apparatus 1 may be performed in steps according to detection information. As a result, if the suspicious person threatens with a weak jet before performing a fraudulent act and still continues the cheating, the continued fraud can be stopped with a strong jet. As a result, an odor can be generated step by step according to the suspicious person's action, and convenience is improved.

  The odor drug of the odor liquid filled in the spray can 11 is preferably one that cannot continue an illegal act against a suspicious person. As the odor drug, for example, a drug having mint odor and wasabi odor may be used as a base, and substances having irritation such as chloroacetophenone, chlorobenzylidenemalononitrile and capsaicin may be used. .

  The spray can 11 may be filled with a dye in addition to the odor drug. As a result, an odor is generated for the suspicious person, and at the same time, the dye is ejected. This makes it easier to identify a suspicious person and enhance the crime prevention effect. As such a dye, a dye that cannot be easily washed when clothes are attached to the skin is preferably used.

  In the present embodiment, the alarm system 2A is configured to include the remote control device 32. However, the present invention is not limited to this, and the alarm system 2A may be configured by the remaining part excluding the remote control device 32. . In addition, the remote control device 32 is not limited to being provided at a location separated from the odor generation alarm device 1, for example, when an input unit that functions as the remote control device 32 is provided at a bank counter, and a suspicious person comes to the counter, It may be configured such that abnormality information is given to the control unit 30 by a reception person at the window operating the input means. As a result, the odor generation alarm device 1 can be remotely operated.
