Abstract

The utility model discloses a device for killing flies and cockroaches. A time-base integrated circuit is connected with a relay; the relay is connected in series between a crystal triode and a direct current power supply; a transformer is connected with the collector of the crystal triode in series; a capacitor connected with the basal pole of the crystal triode forms a high-frequency oscillator; a diode is connected with the secondary pole of the transformer in series; and diode outputs direct-current high voltage to be connected to a fly-catching electric fence or a cockroach killing comb-shaped plate. Aiming at the defects of the prior fly killing and cockroach killing device that the waste is severe and the killing effect is poor, the utility model provides the device for killing flies and cockroaches with electricity conservation and high efficiency. The utility model has the advantages of electrical energy conservation, good fly and cockroach killing effect and convenient use.

Description

Fly eradication, cockroach killer

Technical field

The utility model relate to a kind ofly catch flies, the utensil of cockroach.

Background technology

Fly-killing, cockroach are the important measures of protection environmental sanitation, prevention various diseases, and the fly eradication of electronics high pressure, that cockroach killer has overcome the effective drug expense is big, the shortcoming that environmental pollution is heavy.But it is unsatisfactory that the fly eradication of present employed electronics high pressure, cockroach killer use through reality, and it mainly shows as: 1, the high direct voltage on the high-voltage fence is mostly directly obtained behind voltage multiplying rectifier by civil power 220V, and high pressure is on the low side, and insecticidal effect is relatively poor, and very dangerous.2, the charged electric field that produces of high-voltage fence permanence makes fly, cockroach to electric field higher sensitiveness be arranged and away from high-voltage fence.3, control circuit all fits together into as a whole box with high-voltage fence usually, but places inconvenience because of the change that is subjected to environment position during actual the use, and high-voltage fence cleans also inconveniently at ordinary times, and being not easy to is not again having the place use of civil power.4, all be independent electronics fly eradication, cockroach killer in the market, the insecticidal apparatus of fly eradication is not also arranged, the roach that goes out being combined.

In order to solve the problems of the technologies described above, need to provide a kind of and catch flies, the utensil of cockroach.Not only power saving, effect of killing flies but also good.

Summary of the invention

Technical problem to be solved in the utility model is, and is serious at existing fly-killing device, cockroach killer waste, go out except that the bad shortcoming of effect, and a kind of economize on electricity, fly eradication efficiently, cockroach killer are provided.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of fly eradication, cockroach killer, one time-base integrated circuit connects a relay, relay is serially connected between a transistor and the DC power supply, the collector series connection of this transistor has transformer, the electric capacity that is connected with its base stage constitutes high frequency oscillator, diode of transformer secondary output serial connection, this diode output high direct voltage is connected to catches the fly electrical network or the roach pectinate plate that goes out.

Described time-base integrated circuit is operated in gap state, during work, and connected relay closes, the gap phase, relay disconnects.

The described roach pectinate plate that goes out is, two electrodes are arranged in parallel, and several mutual discontiguous wires be arranged in parallel between two electrodes.

The described roach pectinate plate that goes out is fixed on the support, and horizontal by 45.This angle both can make cockroach climb up the roach pectinate plate that goes out, and can make dead under the cockroach landing on the roach pectinate plate that goes out again.

The utility model has the advantages that: 1. the time end of connecting, save electric energy; 2. electric current is a clearance-type, when not having electric current, and fly, the easier online of cockroach, fly eradication, the roach that goes out are effective; 3. fly eradication, the roach function of going out are combined the function of the compound fly-killing device originally and the roach that goes out; 4. both can adopt high voltage source, and also can adopt low-voltage dc power supplies such as battery, the field of employment is unrestricted.

Embodiment

As Fig. 1-shown in Figure 3, a kind of fly eradication, cockroach killer, one time-base integrated circuit connects a relay, relay is serially connected between a transistor and the DC power supply, the collector series connection of this transistor has transformer, the electric capacity that is connected with its base stage constitutes high frequency oscillator, diode of transformer secondary output serial connection, and this diode output high direct voltage is connected to catches fly electrical network 1 ' or the roach pectinate plate 1 that goes out.

The described roach pectinate plate 1 that goes out is, two electrodes 2 are arranged in parallel, and several mutual discontiguous wires 3 be arranged in parallel between two electrodes 2.

The described roach pectinate plate 1 that goes out is fixed on the support 4, horizontal by 45.This angle both can make cockroach climb up the roach pectinate plate 1 that goes out, and can make dead under the cockroach landing on the roach pectinate plate 1 that goes out again.

During use, at first regulating variable resistor R2, R3 makes the electronic switch relay contact distinguish closed about 2 seconds, disconnect about 10～30 seconds, connect the base loop of vibration inverter circuit transistor VT1 because of the closure of contact, make the base potential rising of VT1 make circuit produce the higher-order of oscillation, inversion is into about the high voltage direct current of 3000V and be transported on the electrical network after the D2 rectification, its insecticidal effect enhancing of raising because of high pressure, the disconnection of contact reduces the base potential of inverter circuit VT1, the circuit failure of oscillation, no high pressure output.In use, in case human body false touch high-voltage fence because of oscillating circuit Q value reduces, and makes the blocking of oscillator, the output high pressure sharply descends, and electrical network be controlled in the long duration by electronic switch not charged, therefore have reliable fail safe.Complete machine divides two parts to form, be control box 5, fly eradication High-Voltage Network and the roach pectination hardboard that goes out, after selecting, be connected with the high-voltage output end of control box 5 respectively during use with high voltage bearing lead, in order also conveniently to use, set up the socket that change over switch K provides external direct current 12V power supply in the circuit in addition in the place that does not have civil power.

Beat several apertures at the roach pectination hardboard central authorities insulation strip place of going out, and plug bamboo let, on bamboo let, insert the bait that cockroach love is eaten.
