Abstract

The invention relates to an ultrasonic dog driving device, which comprises a 9V direct current power source, a button switch AN, a self-excitation resonance oscillation circuit and an ultrasonic output circuit. The self-excitation resonance oscillation circuit comprises a time base integrated circuit (IC) 1, a resistor (R) 1, an R2, a trimming potentiator RP and a capacitor (C)1, wherein the model of the time base IC 1 is NE555. The ultrasonic dog driving device utilizes a device capable of emitting ultrasonic to drive dogs into a special zone or prevent the dogs from being close to human bodies and can enable the fidgety dogs to quickly quiet. Most of dog ears are particularly sensitive or strongly response to sound of frequency within a range of 15-25 kHz so that the ultrasonic sound can frighten and threaten the dogs well. The core circuit of the ultrasonic dog driving device is a large-power ultrasonic generator, and an ultrasonic output transducer utilizes piezoelectric buzzing pieces to generate high-frequency sound, namely the ultrasonic which can enable various dogs not to randomly bake at night and is used for reducing harm caused by driving of the homeless dogs on the street.

Description

The ultrasonic dog expelling device

Technical field

The invention belongs to electronics and technical field of ultrasonic application, is about a kind of ultrasonic dog expelling device.

Background technology

Now more and more people hanker after the pet feeding dog; But must not expressly provide pet dog and get in public places such as a lot of stores, hotel, park; In the resident living sub-district; To night or the late into the night pet dog kyoodle " Wang Wang " and let the people be difficult to have a rest really, some is disliked dog even can damage or propagate rabies to human body, it is the most important to improve consciousness of keeping an eye on and the responsibility of strengthening the dog owner certainly.The present invention is intended to look for another way, with a kind of electronics mode send hyperacoustic device be used to drive pet dog near or the deterrence dog get into particular place, or excited pet dog can promptly be quieted down.

According to the data introduction, many animals are flourishing especially aspect the sense of hearing, can hear the sound of the human upper frequency of can't hear, and the frequency of the audibility range of animal is between 30～50kHz usually, and it is exactly around this principle to make that many business-like insects are driven device.Most of dog ear is responsive especially or respond strongly to the sound of 15 to 25kHz frequencies, and ultrasonic sound has good fright and threatening effect to pet dog.The present invention is by this Research on Principle design; Its core circuit is a supersonic generator that power is bigger, sends high-frequency sound (that is: ultrasonic) with it and drives pet dog, can let pet dog quiet down at night with it; No longer arbitrarily kyoodle, perhaps be used to subdue the invasion that some dislikes dog.

Those are feared that especially the Ms of dog is necessary to carry one and drives the dog device, be used to prevent that those disagreeable dogs are to your invasion and injury on the street.

Below specify the related correlation technique content of this ultrasonic dog expelling device in manufacturing process.

Summary of the invention

Goal of the invention and beneficial effect: the present invention can send hyperacoustic device and drives that dog gets into the specific region or near human body, can make irritated dog quiet rapidly with a kind of.Because of most of dog ear to the sound of 15～25kHz frequency sensitivity or strong reaction especially, so ultrasonic sound has good fright and threatening effect to dog.Core circuit of the present invention is a supersonic generator that power is bigger, and the ultrasonic output transducer uses piezoelectricity singing piece.Send high frequency sounds with it, that is: ultrasonic can let various dogs no longer arbitrarily kyoodle at night with it, is used to subdue or drive the harm of the street vagrant dog.

Technical scheme: the ultrasonic dog expelling device, form by 9V dc source, key switch AN, multi-harmonic self-excited oscillation circuit and ultrasonic output circuit, it is characterized in that:

Multi-harmonic self-excited oscillation circuit: form by time-base integrated circuit IC1, resistance R 1, resistance R 2, trimmer potentiometer RP and capacitor C 1; The model that time-base integrated circuit IC1 adopts is NE555; The anodal VCC of one termination circuit of 4 pin of time-base integrated circuit IC1 and 8 pin and resistance R 1; 7 pin of time-base integrated circuit IC1 link to each other with an end of the other end of resistance R 1, resistance R 2; The end of another termination trimmer potentiometer RP of

Description of drawings

Accompanying drawing 1 is the embodiment circuit working schematic diagram that the present invention provides a ultrasonic dog expelling device; The negative pole of the 9V dc source in the accompanying drawing 1 links to each other with circuit ground GND.

Embodiment

According to being the circuit working schematic diagram and the description of drawings of ultrasonic dog expelling device shown in the accompanying drawing 1; And according to the annexation between the components and parts in the described each several part circuit of summary of the invention, and the components and parts technical parameter described in the embodiment requires to implement to realize the present invention.

The selection of components and parts and technical parameter

IC1 is a time-base integrated circuit, and model is NE555, and packing forms is dual inline type 8 pin DIP encapsulation; Each pin function: 1 pin is circuit ground GND; 2 pin are trigger end; 3 pin outputs; 4 pin preset ends; 5 pin are control voltage; 6 pin thresholdings (threshold value); 7 pin are discharge end; 8 pin are circuit anode VCC;

The resistance of resistance R 1 is 5.8K Ω; The resistance of resistance R 2 is 1.2K Ω; The resistance of trimmer potentiometer RP is 10K Ω;

C1 is an electric capacity of the dacron, and capacity is 10nF; C2 is an electrochemical capacitor, and capacity is 10～22 μ F/16V;

HA is a piezoelectricity singing piece, and diameter ￠ 27.35mm, the diameter of piezoelectricity singing piece can not be greater than 30mm, otherwise the response of ultrasonic highest frequency will be restricted;

AN is a key switch, in an embodiment as power switch.

Circuit production and debugging main points

Require the parameter value of all components and parts accurate, otherwise frequency of oscillation is taken place than about-face;

The circuit welding of the ultrasonic dog expelling device of making at monolithic integrated optical circuit finishes, and all elements are as long as welding is errorless on inspection, and general circuit need not used debugging to connect the 9V dc source and get final product operate as normal;

In the adjustment process, to the adjustment of trimmer potentiometer RP: bigger resistance makes frequencies go lower.Because different dogs can produce reaction to different frequencies, need carry out suitable adjustment to circuit.Test whether circuit can both operate as normal under different frequencies.The frequency that trimmer potentiometer RP and capacitor C 1 produce is about 14HzK to 24kHz; The capacitance of capacitor C 1 is very crucial, and it has determined the frequency of oscillation of multi-harmonic self-excited oscillation circuit, the most ceramic disc capacitor less stable that works together, and error is about about 20%, so the polypropylene capactive of stable performance is adopted in suggestion; Capacitor C 1 capacitance value is bigger than normal, and then the frequency of oscillation of multi-harmonic self-excited oscillation circuit is lower; Because of the capacity of inconvenient trimming capacitor C 1 changes frequency of oscillation, so that suggestion adjustment trimmer potentiometer RP changes the frequency of oscillation of multi-harmonic self-excited oscillation circuit is more convenient;

The complete machine maximum operating currenbt is 110mA, because of complete machine is discontinuity work, so average power consumption is less than 75mA, so can use No. 2 common batteries as dc source;

Another purposes of ultrasonic dog expelling device is, adds a sounds trigger switch to this device, as long as dog kyoodles, this device just startup immediately sends hyperacoustic buzz in night; Through the training of such a period of time, near the dog the ultrasonic dog expelling device just can not kyoodle at night, or opens the ultrasonic dog expelling device, and the dog that is kyoodling will escape at once.
