Description

Kitchen cockroach killing device

Technical field

The utility model relates to a kind of cockroach killing device, especially for the killing device for kitchen cockroach.

Background technology

As everyone knows, the harm of cockroach is all accompanied by people's life always.Along with people's living standard day by day improves, the change of environment and the development of communication, the harm of cockroach increases the weight of increasingly, the more important thing is that it carries various germs, it has also propagated disease in movable.In recent years, the work anti-processed of cockroach more and more causes that people pay much attention to.Therefore, design a kind of cockroach killing device and have very great meaning.

Existing cockroach prevention and cure method is divided into physical method and chemical method.Chemical method uses various medicines to kill cockroach, common are pyrethroid, poison bait, organic phosphor etc.But chemical method but has many harm: easily cause residual, the accumulation of environmental pollution, chemicals and be difficult for degraded to threaten living environment; Use for many years Dalmatian chrysanthemum lipid chemical agent of the same race, made cockroach produce the increasing that extremely strong pesticide resistance causes eradication of cockroaches difficulty; The place of cockroach activity is also the place that human lives, daily life, food deposit, and uses the chemicals roach that goes out to bring the series of problems that threatens human health.Physical method is to utilize food on haftplatte, to stick cockroach for attractant attracts cockroach to climb to mostly, or attracts cockroach to climb to the exposed live metal sheet cockroach that gets killed that powers on.Two kinds of methods all do not have to process for cockroach ootheca, for the corpse of cockroach, can only be to be carelessly dropped into and not process yet, and the get killed method of cockroach of electricity also exists safety problem.Therefore, need to consider environmental protection more, safer, more comprehensive cockroach killing device.

Summary of the invention

Not comprehensive problem and the safety problem in order to improve existing physical method, processed, and consider environmental pollution and human health problems that chemical method is brought, the utility model provides a kind of cockroach killing device, and this device not only safety can bring chemical contamination comprehensively but also not.

The technical scheme that the utility model adopts for its technical problem: the utility model comprises rectangular plastic box, in box, there is lure box, the circuit arrangement of cockroach-killing, and heater and the removable Box for killing cockroach for cockroach corpse and ootheca, processed, the first half of box is heater and removable Box for killing cockroach, mid portion is to place the cockroach lure box of attractant and the comb electrode plate of killing cockroach, cockroach lure box is above comb electrode plate, the latter half of box is for entering roach passage and main circuit device, there is power supply on box surface, work, heat three indicator lamps, main circuit is divided into two parts: a part is that 555 time base circuits that AC/DC convertor connects with photoelectric tube connect the on-off circuit that relay forms again, and wherein 555 time base circuits are that relay power supply makes relay become the switch of operating circuit, the operating circuit that another part is comprised of comb electrode plate and heater circuit, heater circuit consists of temperature detect switch (TDS), fuse and heating resistor.

The beneficial effects of the utility model: use electronic method to kill cockroach, environment friendly and pollution-free; Utilize plastics as the main material of box, safety is not got an electric shock; Heater add corpse and the ootheca of having processed cockroach, prevent the propagation of germ and the procreation of cockroach.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The utility model has designed a kind of kitchen cockroach killing device.In this device, utilize photoelectric tube as a switching mechanism, to control the signal of the input of 555 timers, the closure of output control relay switch of recycling 555 timers reach control operating circuit running whether.Cockroach is the animal of hiding by day and coming out at night, and have people time its activity not strong yet, utilize photoelectric tube can guarantee just to work at the movable timer of cockroach as switching mechanism, utilize to greatest extent the energy not waste again.This device adopts cockroach biological information element as attractant, and both not polluted the environment can harm humans health yet.The heater the adding germ that effectively eradication of cockroaches carries and the ootheca of cockroach, prevent the infection of disease and the procreation of cockroach.

Consult accompanying drawing 1, family expenses 220V power supply converts 12V alternating current to through transformer 1, then changes into 12V direct current to whole on-off circuit power supply through the effect of alternating current-direct current electric bridge 2.Current-limiting resistance 3 in figure falls a part of voltage protection power lights 4 for 4 minutes for power lights, and the resistance of current-limiting resistance 3 is 1K Ω.Electric capacity 5 is in order to protect 555 timers 9, and photoelectric tube 7 and resistance 6 are controlled 9 input end signals of 555 timers.5 pin that discharge capacity 10 connects 555 timers 9 discharge idle.Diode 8 has been also the effect of protection 555 timers 9.The output of 555 timers is received on relay 13, the running of the folding of control relay switch and then control operating circuit, and relay is also with relay switch K1 11 and relay switch K2 14.Fuse 15 prevents the overheated safety problem causing of heater circuit, and temperature detect switch (TDS) 18 is controlled the running of heater circuit.Current-limiting resistance 19 plays protection heating lamp 20, and current-limiting resistance 17 plays comb electrode plate.

As shown in Figures 2 and 3, the utility model kitchen cockroach killing device course of work: after device switches on power, power lights is lighted.While having by day illumination or evening to have illumination, photoelectric tube conducting, the input 2,6 of 555 timers is low level, and timer puts 1, and output 3 is high level, not conducting of relay coil, relay contact disconnects, and operating circuit now no power cannot operate.When evening unglazed according to time, cockroach has come into play, now not conducting of photoelectric tube.The input 2,6 of 555 timers is high level, and 555 timer zero setting ends are effective, timer zero setting, and output 3 is low level, relay coil conducting, relay contact closure operating circuit energising entry into service, portable lamp 12 and heating lamp 20 are lighted.220 V AC powers are discharged to cockroach through relay contact, resistance, make the cockroach getting over be hit unconsciously very soon or shoot dead.The attractant that cockroach is placed in cockroach lure box attracts to crawl in device through entering roach passage 24, when climbing to the comb electrode plate 16 of energising by corona, effect by gravity makes the cockroach of corona fall in Box for killing cockroach from comb electrode plate, now heating resistor 21 is also started working, temperature in Box for killing cockroach arrives 80 ℃, killing cockroach and the germ of carrying thereof, thus the moisture in evaporation cockroach ootheca suppresses the hatching of cockroach nymph.Second day, can pull out removable Box for killing cockroach 23 cockroach corpse is disposed after people get up.What this killing device adopted is domestic power supply power supply, and energising at home just can be used, convenient and swift.
