Description

  The present invention relates to an animal repellent device used for animals such as cats and dogs.

  Conventionally, as this type of animal repellent device, one configured to inject a medicine contained in an aerosol container when an animal approaches a predetermined distance (for example, Patent Documents 1 and 2). reference). In patent document 1, the aerosol container is stored in the inside of a main body case. A pyroelectric infrared sensor is provided on the outer surface of the main body case. An actuator for operating the nozzle of the aerosol container, a power source, and a control board are provided inside the main body case. When it is detected that the animal has approached a predetermined distance by the pyroelectric infrared sensor, the actuator is operated to operate the nozzle of the aerosol container to inject the medicine, thereby giving the animal a repellent effect.

  The animal repellent device of Patent Document 2 is configured in the same manner, and can inject a medicine from an aerosol container stored in the main body case.

JP-A-8-214760 JP 2001-212808 A

  By the way, in the case of the animal repellent device of patent documents 1 and 2, for example, when the aerosol container becomes empty after being used for a long time, a human approaches the animal repellent device for replacement of the aerosol container. At this time, in Patent Documents 1 and 2, since the infrared sensor detects whether or not the animal has approached a predetermined distance, the medicine in the aerosol container is injected at the moment when the human approaches the animal repellent device. End up. In addition, for example, even when a human has to cross or pass through the animal repellent device, the medicine in the aerosol container is jetted if the human approaches the animal repellent device. Such useless injection has a problem that the medicine in the aerosol container is wasted and surprises humans.

  Therefore, when the injection of the medicine is unnecessary as when a human approaches the animal repellent device, for example, an injection prohibition operation such as a human being hitting the hand is performed, and a sound indicating that the injection prohibition operation has been performed is used. It is conceivable that the animal repellent device detects and prohibits the subsequent injection of the medicine.

  However, since the animal repellent device is generally used outdoors, for example, when it rains, there is a possibility that the rain sound is erroneously detected as a sound caused by a human jet prohibition operation. If the detection error occurs, the medicine will not be ejected even if the animal approaches, so that there is a problem that the repelling effect cannot be obtained.

  The present invention has been made in view of such a point, and an object thereof is to prevent wasteful consumption of the propellant in a container when a human deliberately approaches an animal repellent device. It is to prevent the surprise of human beings and to provide the repellent effect when necessary.

  In order to achieve the above object, the present invention is based on the premise that the injection prohibition operation is detected based on the sound generated by the human injection prohibition operation. On the other hand, when the sound is detected a plurality of times within a predetermined time, the injection prohibition control is canceled.

The first invention is
A container containing a propellant,
A switching device for switching between an injection state of injecting an injection from the container and a non-injection state of not injecting the injection,
A sensor that detects whether an animal is within a predetermined distance;
When the sensor detects that the animal is present within a predetermined distance, the control device is set to the injection state, while when the animal is not within the predetermined distance, the control device is set to the non-injection state. An animal repellent device comprising:
Comprising an operation detecting means for detecting an injection prohibition operation performed by a human based on a sound generated by the injection prohibition operation;
When the control unit detects the injection prohibiting operation by the operation detecting unit, the control unit performs the injection prohibiting control for prohibiting the injection by setting the switching device in a non-injecting state even if the animal exists within a predetermined distance. When the detection unit detects a sound two or more times within a predetermined time, the injection prohibiting control is canceled.

  According to this configuration, for example, when a person performs an injection prohibition operation and some sound is generated before the person tries to approach the animal repellent device due to, for example, replacement of a container, the operation detection unit performs injection based on the sound. A prohibited action is detected. Thereby, since the injection prohibition control is performed, the switching device is set to the non-injection state and the injection of the injection is prohibited. Accordingly, the sprayed material in the container is not wasted, and it is possible to prevent the person from being surprised.

  On the other hand, for example, in a situation where the sound is continuously and repeatedly generated like an outdoor rain sound, the motion detection means detects the sound a plurality of times within a predetermined time. In this case, since the injection prohibition control is canceled, when the animal approaches the animal repellent device, the switching device is in the injection state, and the sprayed product in the container is injected, thereby obtaining a repellent effect.

According to a second invention, in the first invention,
The operation detecting means detects the injection prohibiting operation based on a sound generated when a human claps a hand.

  According to this configuration, it is possible to easily use the animal repellent device because the injection of the ejected matter is prohibited by a human hand, and in this case, erroneous detection of the injection prohibiting operation is effectively prevented. Is done.

According to a third invention, in the first or second invention,
Informing means for informing the user that the operation detecting means has detected sound,
The control device is configured such that, when the motion detection means detects a sound, the notification means notifies the fact that the motion detection means has detected a sound.

  According to this configuration, for example, when the user performs an injection prohibition operation, if the sound is small and the operation detection unit does not detect the sound, the notification unit does not notify the user, so the injection prohibition The user can grasp that control is not performed.

According to a fourth invention, in any one of the first to third inventions,
The control device is configured to end the injection prohibition control when a predetermined time elapses after the operation detection means detects the injection prohibition operation.

  According to this configuration, for example, when the animal repelling device is approached in order to perform some work near the animal repelling device, if the injection prohibiting operation is performed in advance, the injection can be prohibited during the work. Therefore, convenience increases. In addition, since the injection prohibition control ends when a predetermined time has elapsed, the animal avoidance effect can be obtained without lapse of a long time with the injection prohibition control.

  According to the first aspect of the invention, the injection prohibition operation is detected based on the sound generated by the human injection prohibition operation. When the injection prohibition operation is detected, the injection is prohibited even if the animal approaches, while the sound The injection prohibition control is canceled when two or more predetermined times are detected within a predetermined time. In this way, when humans deliberately approach the animal repellent device, the explosives in the container are not wasted, and it is possible to obtain a repellent effect while preventing humans from being surprised. Can do.

  According to the second aspect of the invention, since the injection prohibition operation is detected based on the sound generated by the human hand hitting the hand, the erroneous detection of the injection prohibition operation can be effectively prevented while being easy to use. it can.

  According to the third aspect of the invention, since the notification means detects that the operation detection means has detected the sound, the injection prohibition control is performed when the sound due to the user's injection prohibition operation is small and cannot be detected. The user can grasp that this is not done.

  According to the fourth invention, after the injection prohibiting operation is detected by the operation detecting means, the injection prohibiting control is terminated when a predetermined time has elapsed, so that convenience can be improved.

It is a perspective view of the animal repelling apparatus which concerns on embodiment. It is a front view of an animal repellent device. It is a left view of an animal repellent device. It is a top view of an animal repellent device. It is the VV sectional view taken on the line of FIG. It is a block diagram of an animal repellent device. It is a flowchart which shows the flow of control by a control apparatus.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

  FIG. 1 shows an animal repelling apparatus 1 according to an embodiment of the present invention. This animal repellent device 1 is used by being placed on the ground outdoors, and is for preventing animals such as cats and dogs from approaching a certain range.

  As shown in FIGS. 2 and 3, the animal repellent device 1 includes an aerosol container 10, a container cover 15, a leg member 20, and an injection unit 30. As the aerosol container 10, for example, a container made of a pressure resistant container made of an aluminum alloy can be used. By using the aluminum alloy, there is no rust due to rain or the like when the aerosol container 10 is used in an exposed state outdoors, and the weather resistance is improved. In addition, as the aerosol container 10, a tin can may be used in addition to the aluminum alloy. In that case, it is preferable to perform a rust prevention treatment.

  The aerosol container 10 has a cylindrical shape extending in the vertical direction, and the height is set to 10 cm or more, for example. As shown in FIG. 5, a valve mechanism 11 is provided in the upper part of the aerosol container 10. Since the valve mechanism 11 is well known in the art, a detailed description thereof is omitted. However, the valve mechanism 11 includes a stem 11a that moves forward and backward in the vertical direction and a spring (not shown) that biases the stem 11a in the forward direction (upward). When the stem 11a is in the advanced position, the valve mechanism 11 is closed. On the other hand, when the stem 11a is in the retracted position against the biasing force of the spring, the valve mechanism 11 is opened.

  In addition, the aerosol container 10 is formed by caulking and joining metal materials, and the caulking portion formed at the upper portion is a ridge 12 that protrudes in the radial direction of the aerosol container 10 and extends annularly in the circumferential direction. ing.

  The aerosol container 10 contains, for example, a propellant as an animal repellent. In addition, at least one or more of fragrance, ethanol and the like may be accommodated. As the propellant, for example, dimethyl ether or LP gas can be used, and the sound that can be heard by the animal is generated by the injection, and the change in wind and atmospheric pressure that can be felt by the animal can be generated. The animal can be surprised or disliked, and a repellent effect can be obtained. In the case of a fragrance, one that gives off a scent that animals dislike is preferred. In addition, by injecting ethanol, the animal can feel uncomfortable due to the cooling effect caused by the heat of vaporization when attached to the animal, which may provide an avoidance effect.

  The container cover 15 is formed in a cylindrical shape that covers the outer peripheral surface of the aerosol container 10. The lower part of the aerosol container 10 is accommodated in the upper part of the leg member 20, and as shown in FIG. 5, the upper part of the aerosol container 10 is accommodated in the connecting member 25 described later. The container cover 15 has a length that can cover a part other than the part accommodated in the leg member 20 and the part accommodated in the connection member 25 on the outer peripheral surface of the aerosol container 10. The color of the container cover 15 is preferably a white color or a light color with a low sunlight absorption rate. Thereby, it becomes possible to suppress the temperature rise of the aerosol container 10 under fine weather.

  Further, as shown in FIG. 5, the ejection side (upper side) of the ejected matter in the aerosol container 10 is detachably connected to a main body case 50 constituting a part of the ejection section (main body section) 30. A connecting member (detachable member) 25 is fixed. The main body case 50 serves as a cap that covers the stem 11 a of the aerosol container 10. The connecting member 25 requires a tool such as a screwdriver when it is removed from the aerosol container 10 and cannot be easily removed. On the other hand, the user does not use the tool with respect to the injection unit 30 by hand. It can be easily removed. That is, the removal force required when removing the connection member 25 from the aerosol container 10 is set to be larger than the removal force required when removing the connection member 25 from the main body case 50. The detaching force can be arbitrarily set depending on the shape of the connecting member 25 and the body case 50.

  And in the state which attached the connection member 25 to the aerosol container 10, only the connection member 25 of this shape can be attached or detached to the main body case 50 of the injection part 30. FIG. For this reason, for example, the aerosol container 10 to which the connection member 25 is not attached, or the aerosol container 10 to which the connection member of another structure or another shape is attached cannot be attached to the main body case 50 of the injection unit 30. The different aerosol containers and the aerosol containers containing different repellents are not accidentally attached to the main body case 50 of the injection unit 30, and the safety during use can be improved.

  The leg member 20 shown in FIG. 1 and the like can be, for example, a resin molded product. The leg member 20 includes a bottomed cylindrical insertion portion 22 into which the lower portion of the aerosol container 10 can be inserted, and four legs 23, 23,... Protruding outward in the radial direction. The number of legs 23 is not limited to four and can be set to an arbitrary number. The peripheral wall portion of the insertion portion 22 is formed such that the center line extends vertically, and a bottom wall portion (not shown) is provided at the lower end portion. Further, the four legs 23, 23,... Are arranged at substantially equal intervals in the circumferential direction of the insertion portion 22. Each leg 23 is formed so as to protrude outward from the aerosol container 10 in a plan view, thereby making it difficult for the animal repellent device 1 to fall over when placed on the ground or the like. Each leg 23 extends downward from the bottom wall portion of the insertion portion 22 so that the aerosol container 10 can be separated upward from the ground while being placed on the ground or the like.

  As shown in FIG. 5, the injection unit 30 includes a solenoid valve (switching device) 31, a nozzle 32, a pyroelectric infrared sensor 33, a control device 34, a battery 35, and a body case 50 that accommodates these. have. Since the main body case 50 does not contain the aerosol container 10, it is a smaller case than the main body case of the conventional example.

  The main body case 50 is configured by combining a plurality of members made of, for example, a resin material.

  The solenoid valve 31 includes a passage member 40 connected to the stem 11 a of the aerosol container 10, a valve body 41, a movable element 42, a coil 43 for moving the movable element 42, and a spring 44 that biases the movable element 42. And a solenoid case 45 that houses the mover 42, the coil 43, and the spring 44.

  The passage member 40 is fixed in the vicinity of the central portion of the main body case 50 so as not to move with respect to the main body case 50. The passage member 40 is formed with an upstream passage 40 a that opens to the lower surface and extends upward, and a downstream passage 40 b that communicates with the nozzle 32. The upstream passage 40 a and the downstream passage 40 b are injection passages for injecting the animal repellent from the aerosol container 10.

  The stem 11 a is inserted into the upstream end (lower end) of the upstream side passage 40 a of the passage member 40 with the aerosol container 10 attached to the injection unit 30. In this state, the stem 11a is pushed backward by the inner surface of the upstream passage 40a of the passage member 40, so that the valve mechanism 11 of the aerosol container 10 is opened. Further, the inside of the stem 11a and the upstream side passage 40a of the passage member 40 are connected in an airtight manner.

  The valve body 41 is disposed inside the passage member 40 and closes the downstream end of the upstream passage 40a, and can be made of an elastic material such as rubber.

  The solenoid case 45 is fixed to the upper part of the passage member 40 in an airtight manner. The mover 42 accommodated in the solenoid case 45 is made of a magnetic material and has a column shape extending in the vertical direction. The valve element 41 is fixed to the lower end of the mover 42. The mover 42 is disposed in the solenoid case 45 so as to be movable up and down.

  The coil 43 has a cylindrical shape surrounding the outer peripheral surface of the mover 42. The mover 42 moves up and down inside the coil 43. The coil 43 is fixed to the inner surface of the solenoid case 45. A voltage is applied to the coil 43 from the control device 34.

  The spring 44 is disposed above the mover 42 inside the coil 43. The spring 44 applies a load that presses the valve element 41 against the downstream end of the upstream side passage 40a of the passage member 40 and biases the downstream end by biasing the movable element 42 downward. .

  In a state where no voltage is applied to the coil 43 from the control device 34, the movable element 42 presses the valve element 41 against the downstream end of the upstream side passage 40a of the passage member 40 by the biasing force of the spring 44, as shown in FIG. The downstream end is closed. This is a non-injection state. At this time, the biasing force by the spring 44 is set so that the animal repellent of the aerosol container 10 does not flow into the downstream passage 40b of the passage member 40.

  On the other hand, when a voltage is applied to the coil 43 from the control device 34, an upward magnetic force acts on the mover 42. As a result, the mover 42 rises against the urging force of the spring 44 to separate the valve body 41 from the downstream end of the upstream side passage 40a of the passage member 40 and to open the downstream end. This is an injection state. That is, the voltage applied to the coil 43 is set so that the mover 42 can be raised against the urging force of the spring 44.

  The nozzle 32 extends in a substantially horizontal direction. The upstream end of the nozzle 32 is fixed to the passage member 40 and communicates with the downstream passage 40b. The downstream end opening (injection port) 32 a of the nozzle 32 is fixed so as to face the outside at the lower part of the front surface portion of the main body case 50. The front surface portion of the main body case 50 is a portion where the downstream end opening 32 a of the nozzle 32 is located. The shape of the nozzle 32 is not limited to the illustrated one, and may be short or long. The spray range of the animal repellent can be set by the structure of the nozzle 32, and is preferably wider in the horizontal direction than in the vertical direction.

  A circuit board 46 is provided above the nozzle 32 on the front side inside the main body case 50. The circuit board 46 extends in the vertical direction, and a power switch 46a for switching the power ON (ON) and OFF (OFF) is provided at the top. Below the power switch 46a of the circuit board 46, an LED lamp 46b is provided. Further, a control device 34 is provided below the LED lamp 46 b of the circuit board 46, and an infrared sensor 33 is provided below the control device 34. The height of the infrared sensor 33 from the ground is set to be approximately the same as the average cat's body height. Thereby, the detection accuracy of the cat by the infrared sensor 33 improves.

  An operation button 50a made of a membrane sheet for operating the power switch 46a is provided on the upper portion of the front surface of the main body case 50. The operation button 50a is configured to transmit the light from the LED lamp 46b.

  The LED lamp 46 b is an indicator lamp that displays the operating state of the control device 34. The LED lamp 46 b and the downstream end opening 32 a of the nozzle 32 are disposed at the same position in the front surface portion of the main body case 50, that is, in the circumferential direction of the aerosol container 10. As will be described later, the LED lamp 46b is notifying means for notifying the user that sound has been detected, and is for notifying the user that the injection prohibition control is being performed.

  The infrared sensor 33 is a sensor that can detect whether or not an infrared ray emitting object (animal) is present within a predetermined distance, though detailed description thereof is omitted since it is a well-known one. The infrared sensor 33 is disposed in the main body case 50 so as to be directly above the aerosol container 10. For example, the detection range of the animal by the infrared sensor 33 can be set to a range of 2 m or more and 5 m or less from the infrared sensor 33, but is not limited thereto. Although the size of the detection target animal differs depending on the performance of the infrared sensor 33, this embodiment has a performance capable of detecting, for example, a cat or a small dog.

  The infrared sensor 33 is covered with an infrared transmissive cover 50 b provided in the main body case 50. The detection range of the infrared sensor 33 extends from the center of the infrared sensor 33 in the vertical direction and the horizontal direction. In this embodiment, since the animal walking on the ground is the animal to be repelled, a portion extending upward is cut out of the detection range of the infrared sensor 33. That is, a blocking portion 50c as a detection range setting portion that extends downward so as to cover the upper side of the infrared sensor 33 when viewed from the front is provided at a portion where the infrared sensor 33 is disposed in the main body case 50. Thereby, for example, even if a bird or the like flies near the animal repelling device 1, it is not detected as a repelling target animal. Further, for example, even when a heated object (such as laundry under sunlight) moves above the infrared sensor 33, it is not detected as an animal to be avoided, and thus erroneous detection can be prevented.

  Moreover, since the power switch 46a is provided above the infrared sensor 33, when the power switch 46a is operated, the infrared sensor 33 can be prevented from detecting a human hand as an animal to be avoided.

  The battery 35 is housed on the back side inside the main body case 50. The battery 35 is disposed directly above the aerosol container 10. The battery 35 is connected to the circuit board 46. The battery 35 can be replaced by opening and closing a lid 50e provided in the main body case 50.

  The main body case 50 is provided with a buzzer 46e (shown only in FIG. 6). As the buzzer 46e, an electronic buzzer that emits a known electronic sound can be used, but a speaker may be used in addition to this. The buzzer 46e is for informing that the injection prohibition control described later is being performed.

  Further, the main body case 50 is provided with a sound sensor 46f (shown only in FIG. 6). The sound sensor 46f can be composed of a sensor that detects sound pressure, and at least detects, for example, a sound that a human has struck at a distance of about 5 m from the animal repellent device 1 (a sound generated by an ejection prohibiting operation). It has a sensitivity that can be achieved. The separation distance between the human and the animal repellent device 1 at this time is set to a long distance so as to be outside the detection range of the infrared sensor 33. The predetermined sound detected by the sound sensor 46f can detect, for example, a voice uttered by a human being or a whistle in addition to a sound of a human clapping, so that a sound intentionally generated by a human can be detected. It is configured. In addition to the predetermined sound, the sound sensor 46f also detects various environmental sounds such as rain sounds, thunder sounds, and engine sounds of automobiles and motorcycles.

  A signal is output to the control device 34 when the sound sensor 46f detects a sound pressure above a predetermined level. The above-described clapping, vocalization, and whistling are examples of an injection prohibiting operation performed by a human, although details will be described later. The sound sensor 46f is an operation detecting unit that detects an injection prohibiting operation performed by a person based on sound, and may be a microphone, for example.

  The control device 34 is composed of a known microcomputer or the like, detects input signals from the infrared sensor 33 and the sound sensor 46f and the operating state of the power switch 46a, and controls the solenoid valve 31, the LED lamp 46b and the buzzer 46e. Configured to control. When the control device 34 determines that the power is turned on based on the operation state of the power switch 46a, the control device 34 starts supplying power to the infrared sensor 33.

  The contents of control by the control device 34 will be described according to the flowchart shown in FIG. This control starts when the power switch 46a is turned on. After the power switch 46a is turned on, the process proceeds to step S1 to determine whether or not the target animal has been detected. When an animal enters the detection range of the infrared sensor 33 with the power turned on, the control device 34 determines that the animal is detected within the predetermined distance by the infrared sensor 33 and proceeds to step S2. . In step S2, a voltage is applied to the coil 43 of the solenoid valve 31, and the solenoid valve 31 is opened for a predetermined time (T1) to be in an injection state. The predetermined time (T1) can be set to, for example, not less than 0.5 seconds and not more than 2 seconds, and is set to 0.8 seconds in this embodiment. The predetermined time (T1) is not limited to the above range. Further, the solenoid valve 31 may be opened and closed a plurality of times.

  When the solenoid valve 31 is in the injection state, the animal repellent in the aerosol container 10 flows from the stem 11a through the upstream passage 40a of the passage member 40 of the injection unit 30 into the downstream passage 40b. The animal repellent that has flowed into the downstream passage 40b flows into the nozzle 32 and is ejected from the downstream end opening 32a. Since the animal exhibits repellent behavior by the sound and wind at this time, a repellent effect is obtained.

  The spray range of the animal repellent can be changed depending on the structure of the nozzle 32 and components such as the propellant contained in the aerosol container 10. In this embodiment, the animal repellent is injected in a range substantially equal to the detection range of the animal by the infrared sensor 33. After step S2, the process returns and the determination in step S1 is made.

  On the other hand, if no animal is detected by the infrared sensor 33 in step S1, the determination is NO, that is, the control device 34 determines that there is no animal within a predetermined distance. In this case, a voltage is applied to the coil 43 of the solenoid valve 31. Is not applied, the solenoid valve 31 is left in the non-injection state, and the process proceeds to step S3.

  In step S3, it is determined whether or not a sound (predetermined sound) generated by the human being by the ejection prohibiting operation is detected by the sound sensor 46f. If NO is determined in step S3 and no sound is detected, the process proceeds to step S1.

  On the other hand, if it is determined as YES in step S3 and the sound is detected by the sound sensor 46f, the process proceeds to step S4. In step S4, the LED lamp 46b is turned on. Since the light from the LED lamp 46b passes through the operation button 50a, it is possible to grasp whether or not the animal repellent device 1 is turned on from a remote place. Moreover, since the LED lamp 46b and the injection port 32a are located in the front part of the main body case 50, the approximate position of the injection port 32a can also be grasped by the light of the LED lamp 46b. Similarly, the position of the infrared sensor 33 can be grasped. In addition, the user can be notified that the sound has been detected by the sound sensor 46f. In other words, for example, when the user performs the injection prohibition operation, if the sound is small and the sound sensor 46f does not detect, the LED lamp 46b does not notify the user, so the injection prohibition described later is performed. It becomes possible for the user to grasp in advance that the control is not performed.

  In step S5 following step S4, it is determined whether or not the sound is detected again within one second from the time when the sound sensor 46f detects the sound in step S3. The time of 1 second may be an arbitrary time between 0.5 seconds and 3 seconds, for example.

  If it is determined as NO in step S5 and no sound is detected again, it can be determined that the user is in an injection prohibiting operation. Therefore, the process proceeds to step S6, and the buzzer 46e remains with the LED lamp 46b turned on. Also turn on. The sound emitted from the buzzer 46e is preferably an intermittent sound, for example. At the same time, in step S6, the infrared sensor 33 is turned off. Thereby, even if a human approaches the animal repellent device 1, the solenoid valve 31 will not be in an injection state, so that the injection in the aerosol container 10 is not injected.

  In other words, if it is necessary to approach the animal repellent device 1 with the power turned on, if a person who tries to approach it makes a predetermined sound by, for example, hitting the hand in advance, it will be detected by the sound sensor 46f. Is detected, and the control device 34 performs the injection prohibition control for prohibiting the injection by setting the switching device 31 to the non-injection state even when the animal exists within a predetermined distance. And it is alert | reported to the periphery by LED lamp 46b and the buzzer 46e that injection prohibition control is performed.

  Therefore, it becomes possible to suppress the injection of a jet against a human being, so that the jet is not consumed unnecessarily and the human is not surprised. This injection prohibition control is particularly effective when approaching the animal repellent device 1 in an attempt to turn off the power, or when passing around the animal repellent device 1 when replacing the aerosol container 10.

  In step S8 following step S6, it is determined whether or not a predetermined time (T2) has elapsed. Although the predetermined time (T2) is 3 minutes in this embodiment, the predetermined time (T2) is not limited to this, and can be set to, for example, 30 seconds or more and 5 minutes or less. In step S8, the process waits until a predetermined time (T2) elapses, and the infrared sensor 33 remains OFF during that time. In addition, since a sound is emitted from the buzzer 46e and the LED lamp 46b is lit, the surrounding people know that the injection prohibition control is being performed.

  When the predetermined time (T2) has elapsed, YES is determined in step S8, and the process proceeds to step S9. In step S9, the LED lamp 46b is turned off and the buzzer 46e is also turned off. Then, the infrared sensor 33 is turned on. Therefore, the injection prohibition control can be terminated when a predetermined time (T2) has elapsed after detecting the injection prohibition operation. Then, it returns and progresses to step S1.

  On the other hand, a case will be described where, in step S5, the sound is detected again within one second from when the sound sensor 46f detects the sound in step S3. The fact that the sound sensor 46f detects the sound again within one second from the time when the sound sensor 46f detected the sound in the above step S3 means that the sound is continuously and repeatedly generated as in the case where the rain sound is generated, for example. It is a situation. In this case, since the user does not perform the injection prohibition operation, it is not necessary to perform the injection prohibition control. In this embodiment, YES is determined in step S5, and the process proceeds to step S7. The process returns to S1. In step S1, the above-described determination is performed.

  In the case of a rain sound, since the sound is detected also in step S3 which has been returned after step S5, step S7 and step S1, the process proceeds again to step S4, step S5 and step S7. That is, in a situation where the sound is repeatedly generated repeatedly, the sound is detected a plurality of times within a predetermined time. In this case, since the process does not proceed to step S6, the above-described injection prohibition control is canceled. In other words, when the animal approaches the animal repellent device 1, a spray is injected, and a repellent effect is obtained.

  Examples of sounds that are continuously and repeatedly generated include, for example, thunder sounds, automobile and motorcycle engine sounds, dog squealing, etc., and if such sounds occur, the injection prohibition control can be canceled. it can.

  As described above, according to the animal repellent device 1 according to this embodiment, the solenoid valve 31, the infrared sensor 33, and the control device 34 for switching the injection state are attached to the upper side of the aerosol container 10 having a predetermined height. The large case that accommodates the aerosol container as in the conventional example is not necessary, and the animal repellent device 1 can be miniaturized, and the degree of freedom of the installation location can be improved. Further, by attaching the infrared sensor 33 to the upper side of the aerosol container 10, it is possible to improve the detection accuracy of animals such as cats and dogs having a certain body height, and a sufficient avoidance effect can be obtained.

  In addition, when the injection prohibition operation is detected based on the sound generated by the user's injection prohibition operation, and the injection prohibition operation is detected, the injection is prohibited even if the animal approaches, while a plurality of sounds are generated within a predetermined time. The injection prohibition control is canceled when it is detected twice. Thereby, when a user deliberately approaches the animal repellent device 1, the repellent effect is necessary while preventing the waste of the propellant in the aerosol container 10 from being wasted and surprised humans. You can get it at any time.

  Further, since the injection prohibiting operation is detected based on the sound generated by the user's clapping, erroneous detection of the injection prohibiting operation can be effectively prevented while allowing easy use.

  Further, since the sound sensor 46f detects that the sound has been detected by the LED lamp 46b, for example, when the sound due to the user's injection prohibition operation is low and cannot be detected, the injection prohibition control is not performed. Can be grasped by the user.

  Moreover, since the injection prohibition control is terminated when a predetermined time has elapsed after detecting the user's injection prohibition operation, the convenience can be improved.

  In the above embodiment, the infrared sensor 33 is used as a sensor for detecting whether or not an animal is present within a predetermined distance. However, the present invention is not limited to this, and various sensors can be used.

  In the above embodiment, the solenoid valve 31 is used as a switching device for switching between an injection state in which the animal repellent is injected from the aerosol container 10 and a non-injection state in which the animal repellent is not injected. Instead, for example, the cam mechanism may be used to push down the stem 11a of the aerosol container 10.

  Moreover, in the said embodiment, although the power switch 46a is provided in the front part of the main body case 50, you may provide not only in this but in the upper surface part of the main body case 50, for example. Further, the power switch 46 a may be provided above the infrared sensor 33 in the side surface portion of the main body case 50.

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  As described above, the animal repelling apparatus according to the present invention can be used, for example, when driving away animals such as cats and dogs outdoors.
