Abstract

The utility model relates to an electronic cockroach catcher, which comprises a casing, wherein the inside of the casing is provided with a containing space which presents a frustum shape; a PTC heater, a heat conductor and an electrode slice are arranged in the bottom of the casing, below the containing space; the wall surface of the casing is provided with an external power plug jack and a power switch. The electronic cockroach catcher has the advantage that a warm and wet containing space can be generated so that the cockroaches can be prompted to gather in the containing space of the casing, achieving the purpose of catching and killing cockroaches.

Description

The electronics cockroach catching device

Technical field

The utility model relates to a kind of cockroach catching device, especially relates to the electronics cockroach catching device of a kind of use positive temperature coefficient resistor heater (PTC heater) as thermal source.

Background technology

In many places, cockroach is overflowed, and has produced the articles for use that cockroach is killed in a large amount of being used for thereupon.Insecticide is a kind of modal roach articles for use that go out, yet the environmental hazard that insecticide had is known by the public already.And long-term use of insecticide will impel cockroach to develop immunity to drugs, thereby the roach effect of going out is reduced widely.

Other has a kind of roach articles for use that go out of sticking roach plate class, and it is to smear the binder that one deck has bait in the bottom of a box body, when the bottom of box body is climbed in the attraction that is subjected to bait when cockroach, reaches the effect of catching and killing thereby just can be attached on the sticking roach plate.But sticking paper long term exposure wherein can cause viscosity significantly to descend even lost efficacy in air, and sticking roach plate can only use and once just need to change, thereby economical inadequately.

Therefore there is the people to invent a kind of not consumes energy, the free from environmental pollution and cockroach catching device that can use repeatedly, this cockroach catching device is by constructing a box body with unilateral gate, in the accommodation space of these box body central authorities, place bait, the smell that distributes by bait attracts cockroach to climb in this accommodation space, and because box body has the unilateral gate that can only advance to go out, therefore cause cockroach to climb out of, thereby recycling discharge or the mode such as drowned in the water directly cockroach poured into reach the purpose of killing black beetle.Yet this cockroach catching device effect in actual use is very limited, and its subject matter is the selection of bait very difficult.In the ordinary course of things, mostly bait is to be selected from food, however the place that can make cockroach survival some not enough clean environments often, and all having in these places in a large number can be for the food of cockroach survival, so food is very limited to the attraction of cockroach.And be hidden in again in the box when this food bait, only when giving out taste and attract cockroach, the attraction of the bait that weakened more.Therefore, can be attracted and the cockroach that is drilled in the box is very limited though this box with unilateral gate can reach the purpose that makes the cockroach only import but no export really.And the structure more complicated of this cockroach catching device, manufacture rather difficult.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and obvious results electronics cockroach catching device.It is to utilize cockroach to like the moistening habit of warm happiness, designs a kind of housing that can produce the warm and moist environment, cockroach is accumulated in the housing, thereby reach the purpose of catching and killing.

For achieving the above object, the utility model provides a kind of electronics cockroach catching device, it is characterized in that including a housing, has an accommodation space in the inside of this housing, this accommodation space is taper type, below this accommodation space, be provided with PTC heater, heat carrier and electrode slice in the bottom of this housing, external power supply jack and power switch are installed on the wall of housing.

Described electronics cockroach catching device, the surface temperature that it is characterized in that described PTC heater is 40～50 ℃, its normal temperature resistance is 500～1500 ohm.

Aforesaid electronics cockroach catching device, because its place, centre position in the bottom of housing is provided with a PTC constant temperature chip heater, and this PTC heater can be controlled at temperature between 40～50 ℃ that cockroach likes, and has therefore built a kind of environment that cockroach perches that is suitable for.Can also build a kind of moistening environment by in accommodation space, adding an amount of water in addition.Can also come trapping cockroach thus by adding the food that cockroach is liked.Climb into or drop into the bottom section of accommodation space of warm housing when cockroach after, because this accommodation space is the shape of frustum, therefore make cockroach be easier to enter and be not easy to climb out of, at this moment only need cut off the electricity supply, cockroach is killed be got final product by in housing, spraying the modes such as roach liquid medicine or water filling of going out.

Embodiment

As shown in Figure 1, this electronics cockroach catching device 1 comprises a housing, in the inside of this housing, have the accommodation space 6 of a taper type, between the bottom surface of the bottom surface 5 of this accommodation space 6 and this housing, be provided with as shown in Figure 3 PTC heater 7, heat carrier 8 and electrode slice 9.What heater of the present utility model adopted is the positive temperature coefficient resistor pottery, i.e. the PTC pottery.It is characteristics of having utilized the automatic constant-temperature that PTC heater 7 had, does not therefore need to be provided with in addition temperature control system, can be with temperature constant in a predetermined scope.Preferably, the surface temperature of the PTC heater 7 in this example is 40～50 ℃, and its normal temperature resistance is 500～1500 ohm.This temperature is more suitable for cockroach and perches.Heat carrier 8 has two functions promptly, as heat carrier, the heat that PTC heater 7 is produced is delivered to the bottom surface 5 of accommodation space by it, the bottom surface 5 of this accommodation space is to be made by the good conductor of heat, guaranteed that like this temperature of PTC heater generation can concentrate on the bottom of this accommodation space, thereby help guiding cockroach to climb into and drop into this accommodation space inside, and be trapped in the bottom of this accommodation space from the opening part of housing; As conductive electrode, play electric action in the one side of PTC heater 7, draw lead to power supply from pin.Electrode slice 9 is the conductive electrode of the another side of PTC heater 8.Power switch 3 plays the break-make power supply.External power supply jack 2 joins with AC power cord 4, with turn-on power.

Figure 2 shows that the circuit diagram of this electronics cockroach catching device.As shown in the figure, this circuit is by PTC heater 7, and power switch 3 and power series form.

Claims
