Each electrode component is composed of conducting bars which are arranged in a staggered way, and every two adjacent conducting bars have identical voltage difference.

Description

Device for luring and killing cockroach

The utility model relates to a kind of device that harmful insects such as cockroach are used of traping and kill.

The method of existing kill harmful insect comprises that mainly medicine poisoning and high-frequency electrical kill two kinds, and the former is because the poisonous bait of use or spray poisonous solution, and as easy as rolling off a logly causes the person poultry poisoning; The latter then is driveing, the bigger insect that the object cockroach is such, and predating efficiency is very poor.

The purpose of this utility model is that a kind of cockroach eradication device that lures that has trapping and kill function will be provided, this lures cockroach eradication device at first to utilize bait that cockroach is lured to its housing, the structure of housing is suitable for cockroach and enters, but be unfavorable for that it escapes from, also be provided with electrod assembly in the housing, the cockroach that will drop down onto after being used to switch in the housing is electrocuted.

For achieving the above object, the cockroach eradication device that lures of the present utility model comprises housing, be installed on bait and electrod assembly in the housing, on housing, be provided with the push switch that adds high voltage to the part of electrod assembly, housing is made up of big mouthful of downward cone barrel main body and the protective cover that is positioned on the main body top, between protective cover and cone barrel main body are suitable for reading, leave the slit that enters for cockroach, protective cover is inverted dish type, that is to say, the space that is surrounded by main body and protective cover is taper, and inner walls is smooth, thereby in a single day cockroach enters and just be difficult to therefrom escape from again.In the chassis central authorities that match with the big mouth of lower body part one female parts is arranged, be used for setting-in bait box from the outside, be provided with electrod assembly around the female parts, electrod assembly comprises the second portion on first that is positioned at chassis inner surface and the shallow barrel that is positioned on the chassis, second portion has low pressure usually, so that cockroach is hit unconsciously, make it to escape from the zone that shallow barrel surrounds, first is by the control of the press button on housing power on/off, when button is pressed, this part adds high pressure, so that cockroach is electrocuted, because the cockroach volume is less, electrod assembly adopts staggered slice structure, a ground connection in the adjacent slice, another connects low pressure or high pressure.

Owing to adopted luring of bait, therefore restriction of housing (or claiming trap effect) and electric shock, of the present utility modelly lure cockroach eradication device killing black beetle and other insect expeditiously.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done description more specifically.

Fig. 1 is according to the half sectional view that lures cockroach eradication device that the utility model proposes;

Fig. 2 and 3 is structure charts that lure the electrod assembly of cockroach eradication device shown in Figure 1;

Fig. 4 is this electrical schematic diagram that lures cockroach eradication device.

As shown in Figure 1, this lures cockroach eradication device to comprise shown in housing 10, bait 20 and electrod assembly 30 and the 31(thick dashed line).Housing 10 is made up of cone barrel main body 11, plate-like protective cover 12 and chassis 17, protective cover 12 is pegged graft to cooperate by jaw on it 13 and the corresponding pole 14 on the main body and is fixed in the main body top, protective cover 12 usefulness transparent plastics are made, so that quantity and the death condition of cockroach in the observation main body, when need are poured out the cockroach in the main body, protective cover 12 under dialling, main body is got final product, because main body has the suitable for reading of an opening.The slit 15 that enters for cockroach is arranged between main body 11 and protective cover 12, in addition, in the present embodiment, also leave slit 16 on main body 11 tops, so that cockroach enters.Assemble described chassis 17 at main body 11 end openings, there is a female parts 18 in chassis 17 central authorities, and female parts 18 outsides are surrounded with shallow tube 19.Perforate 18a is arranged at the top of female parts 18, is contained in the smell of the bait 20 in the bait box 21 for diffusion.Be provided with electrod assembly 30 and 31 on shallow tube 19 walls and on the chassis inner surface between shallow tube and the female parts 18.

Shown in Fig. 2 and 3, electrod assembly 30 and 31 is to be made of staggered conductor bar, a ground connection in the adjacent conductor bar, and another root connects high voltage.Electrod assembly 31 shown in Figure 3 is expanded views, and in fact, it is to be formed on the annular inner wall of shallow tube 19 by structure shown in Figure 3, A, and A ' end links to each other, B, B ' end links to each other.Can guarantee so all has same pressure differential between every adjacent two conductor bars, and cockroach touches adjacent arbitrarily two conductor bars and all can or electrocute by electrical stunning.

Fig. 4 shows this electrical schematic diagram that lures cockroach eradication device, as can be seen because the dividing potential drop effect of resistance R 1-R4, between A, B end (being between conductor bar) when having cockroach to exist, voltage difference therebetween is lower.And when K switch (switch is located on the housing, and is not shown) was connected, the voltage difference of P, Q end but was higher, was enough to kill any insect.Certainly, electrod assembly 30 and 31 connects identical voltage and also is fine.

Claims (1)

1. A kind of cockroach eradication device that lures, comprise housing 10, bait 20 and electrod assembly 30, it is characterized in that, housing is by big mouthful of downward cone barrel main body 11, dish type protective cover 12 chassis are formed, protective cover 12 is pegged graft with removably and is fixed in main body 11 tops, and and main body 11 tops between separate the slit 15 that enters for cockroach, there is a female parts 18 in chassis 17 central authorities, in this part, be embedded with the bait box 21 of containing bait 20 from the outside, be surrounded with a shallow tube 19 around the female parts, be provided with electrod assembly 31 and 30 on the inwall of shallow tube and on the chassis inner surface between shallow tube and the female parts, each electrod assembly is made up of staggered many conductor bars, for each electrod assembly, between each adjacent conductor bar same voltage difference is arranged.
