DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric detection device for detecting the presence of small pests such as cockroaches in a kitchen or the like.

[0002]

2. Description of the Related Art In removing cockroaches in a kitchen or the like, a habitat state survey is conducted in advance. At the time of this investigation, conventionally, a sticky cockroach catcher or the like has been used, but according to that, if one cockroach is captured by the catcher and restrained, the other cockroach shows an abnormal reaction, Accurate situation investigations are not possible.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to detect a small pest such as a cockroach without quantitatively detecting its inhabitation state, and to improve the detection accuracy.

[0004]

According to the present invention, a passage for small pests such as cockroaches is provided at the bottom of a case, and a light-emitting device and a light-receiving device are arranged at opposing positions crossing the passage. It is operated intermittently by an oscillator, the output of the oscillator and the output of the photodetector are checked by a synchronization detection circuit, and when the outputs do not match, a timer circuit is started by the output of the synchronization detection circuit. The number of inhabitants is counted.

[0005]

According to the above construction, once a cockroach or the like is detected by the light emitter and the light receiver, the detection operation is interrupted for a predetermined timer time by the timer circuit.
Since the movement of one cockroach reduces the number of counts of two or more times, the number of cockroaches and the like can be detected more accurately.

[0006]

1 to 5 show a case 2 of a detecting apparatus 1 for detecting small pests such as cockroaches.
7 shows an electrical configuration.

The case 2 has a box shape as a whole, forms a space for forming an electric circuit therein, has a cockroach passage 3 at the bottom, and has a light emitting device at an opposing position crossing the passage 3. 4 and a light receiver 5 are provided in an opposed state.
The light emitter 4 is an infrared light emitter, and the light receiver 5 is a sensor that detects the infrared light. In the center of the passage 3, the bottom plate 10 is located at a position where the light emitting device 4 and the light receiving device 5 face each other.
Are provided integrally, and a ridge 11 is integrally formed in a direction connecting the light emitting device 4 and the light receiving device 5 on the upper surface thereof. When a small pest, such as a cockroach, gets over the ridge 11, it blocks the infrared rays from the light emitting device 4 so as not to reach the light receiving device 5. The ridges 11 are provided in order to prevent cockroach excrement from being deposited at the position where infrared rays pass.

Next, as shown in FIG. 6, the light emitting device 4 is connected to an oscillator 9, and the oscillator 9
Is connected to one of the input terminals. The light receiver 5 is
The amplifier 12 is connected to the other input terminal of the synchronization detection circuit 6. The synchronization detection circuit 6 can be connected to a timer circuit 7, and the timer circuit 7 can be connected to an external relay circuit 14 or the like via a counter 8 and a connector 13.

As shown in FIG. 7, these circuits are operated by a battery 15, and are turned on when a switch 16 is turned on. The battery 15 has a low voltage detection circuit 17 and a low voltage indicator lamp 18.
When the operating voltage is lower than the operating voltage, it can be visually confirmed by lighting the low-voltage display lamp 18.

The cockroach detecting apparatus 1 having the above-described configuration is installed on a floor in an investigation area such as a kitchen, and a cockroach attractant is placed on a bottom plate 10 as necessary. Thereby, the cockroaches gather near the passage 3 in response to the smell of the attractant. When the switch 16 is set to the ON state, the oscillator 9 starts an oscillating operation, and causes the light emitter 4 to operate intermittently, for example, by an oscillating output as shown in FIG.

When the light emitter 4 is emitting infrared light,
When the cockroach passes over the ridge 11, the infrared light is blocked, and the light receiver 5 does not detect the infrared light when the light is blocked. For this reason, the synchronization detection circuit 6 detects the light-shielded state of infrared rays, that is, the mismatch state between the output of the oscillator 9 and the output of the light receiver 5, generates an output, and operates the timer circuit 7.

The timer circuit 7 operates from the time when the output of the synchronization detection circuit 6 is received, and invalidates the output from the synchronization detection circuit 6 for a predetermined timer time. Therefore, even if the cockroach detected once has reciprocated between the light emitting device 4 and the light receiving device 5, it is not counted, so that it is not counted.
A malfunction in which one cockroach is counted twice or more can be prevented beforehand. This is a device for improving the detection accuracy in consideration of the cockroach activity characteristics. Note that this timer time is determined by the controller 1 attached to the timer circuit 7.
9 can be set to an appropriate time.

The counter 8 has an output of the timer circuit 7,
For example, by counting the fall of that output,
The number of cockroaches detected can be visually confirmed from the outside by the display device 20. The count value can be returned to zero by the reset switch 21.

The output of the timer circuit 7 can also be output to an external relay circuit 14 or the like. If the relay circuit 14 is used as an on / off control of the insecticide spraying device, the insecticide spraying device sprays the insecticide when the cockroach is detected, and exterminates it.
Therefore, the detection device 1 for small pests such as cockroaches
Can be used not only for investigating habitats such as cockroaches, but also for controlling the on / off of the extermination device. It should be noted that the switch 16, the low-voltage indicating lamp 18, the controller 19, the reset switch 21, and the connector 13
Are attached to the case 2 at a position with good operability and visibility as shown in FIGS. 1 to 5.

[0015]

According to the present invention, the asynchronous detection operation is facilitated because of the pulse light emission type, and once the detection operation is performed, the detection operation is in a standby state for a timer period, and the power consumption during that time is provided. , The battery life is extended, the battery can be operated for a long time, and once the detection operation is performed, the counting operation is not performed for a predetermined timer time. Can prevent malfunction due to reciprocating movement of cockroaches, etc. and improve data reliability,
There are features.
