Description

[Detailed explanation of the invention] Industrial application field This invention is based on the speed of movement of the tape-shaped insecticidal pine,
This invention relates to an electric insect killer that enables temperature control of a heating element.

Conventional technology The amount of volatilization of the insecticidal ingredient suitable for the size of the room can be achieved by using a conventional tape-shaped insecticidal mat and changing the moving speed of the tape-shaped insecticidal mat into multiple stages depending on the size of the room where it is used. An application for an electric insecticide capable of producing the same has already been filed in Utility Model Application No. 1983-97950 (Utility Model Application No. 1987-7773).

Problems to be Solved by the Invention However, the above-mentioned conventional electric insect killer only changes the moving speed of the insecticide tape, but does not change the temperature of the heating element, and therefore has the following problems.

In other words, if the heat generation temperature of the heating element is set low and the tape-shaped insecticidal mat is moved over this heating element at a low speed, the insecticidal component will be volatilized more fully than the tape-shaped insecticidal mat, but the tape-shaped insecticidal mat If the moving speed of the pine becomes high, the tape-shaped insecticidal pine will not be sufficiently heated to the volatilization temperature of the insecticidal component, and an efficient insecticidal effect cannot be expected.

On the other hand, if the heat generation temperature of the heating element is set high and the tape-shaped insecticidal mat is moved over this heating element at high speed, the insecticidal ingredients will be volatilized more fully than the tape-shaped insecticidal mat; When the speed of the tape-like insecticidal pine becomes low, the insecticidal ingredient is volatilized in the first half when the tape-shaped insecticidal pine comes into contact with the heating element, but in the second half, the insecticidal ingredient is thermally decomposed and the insecticidal effect is significantly reduced.

This invention was made for the purpose of improving the above-mentioned problems.

Means and action for solving the problem By controlling the heat generation temperature of the heating element in conjunction with the moving speed of the tape-shaped insecticidal mat, a heat generation temperature suitable for volatilization of the insecticidal component can be obtained, thereby increasing the insecticidal effect. An electric insect killer with increased

A motor 10 is attached to this motor receiver 9, a collar body 12 is attached to an output shaft 11 of the motor 10, and an engaging portion 13 is formed on the output shaft 11.
Further, an air hole 14 is formed in the bottom part 6 of the lower case body 3, and a notch part 16 is formed in the upper edge of the rear wall part 15 of the lower case body 3.

The upper case 1 includes an upper case main body 17, and a cover mounting portion 19 consisting of an opening is formed in the upper surface portion 18 of the upper case main body 17.

In addition, locking hooks 22 are provided at the four corners of the upper surface 18 of the upper case body 17, and a motor presser 23 is provided protruding from the upper surface 18 of the upper case body 1. A notch 25 is formed at the lower edge of the portion 24.

Then, the locking hook 22 is inserted into the locking hole 5 of the locking portion 4.
The upper case 1 is fixed to the lower case 2 by being engaged with the insecticide main body 40.

Further, in the drawing, reference numeral 41 denotes a cover. The cover 41 has an opening 42 formed therein, a bridge 20 passing through the opening 42, and a mat presser 21 formed on the lower surface of the cover 41.

This cover 41 is detachably attached to the cover attachment part 19.

On the other hand, 27 is a power supply cord, and a plug (not shown) for connecting to a power source is attached to one end side. The other end of the cord 27 is introduced into the insecticide main body 40 through the notches 16 and 25, and is connected to a control circuit 45 installed within the insecticide main body 40. The above control circuit 4
5 is a voltage regulator as shown in FIG. 17, for example, and the heating element 7 and motor 10 are connected in parallel to the output side of this voltage regulator 45'. Further, the voltage regulator 45' is linked to a changeover switch 26 attached to the top surface 18 of the upper case body 17, and by changing the changeover switch 26, the rotational speed of the motor 10 and the heat generation temperature of the heating element 7 can be controlled. , are controlled so that they maintain a constant relationship with each other.

In the drawing, 28 is a winding drum, and 29 is a feeding drum.

The winding drum 28 is constructed by attaching a collar body 30 to one end of a shaft 36 and forming a locking hole 38 at the other end of the shaft 29.

The feeding drum 29 is formed by attaching flanges 32 and 33 to both ends of a shaft 31.

A tape-shaped insecticidal mat 34 is wound between each of the winding drums 28 and the feeding drums 29.

Next, the action will be explained.

First, the cover 41 is removed from the cover attachment part 19 of the upper case 1, and the feeding drum 29 with the tape-shaped insecticidal mat 34 wound thereon is attached to the drum receiver 8.
Then, the winding drum 28 is connected to the motor 10 by locking the locking portion 13 of the output shaft 11 of the motor 10 in the locking hole 38 of the winding drum 28, and the end of the winding drum 28 is attached to the drum receiver 35. Installing.

The tape-shaped insecticidal mat 34 is fed out from the feeding drum 29, placed along the heating element 7, the fed end is wound around the winding drum 28, and the cover 41 is attached to the cover mounting portion 19.

In this case, the mat presser 21 serves to press down the tape-shaped insecticidal mats 34 on the left and right sides of the heating element 7.

Next, switch 2 according to the size of the room.
6 to set the moving speed of the tape-shaped insecticidal mat 34 and the heat generation temperature of the heating element 7.

That is, if the room used is large, a large amount of the insecticidal component must be volatilized, so the moving speed of the tape-shaped insecticidal mat 34 is increased. A motor 10 that moves the tape-shaped insecticidal mat 34 and a heating element 7
are both connected to the control circuit 45, and when the moving speed of the tape-shaped insecticidal mat 34 is increased, the heat generation temperature of the heating element 7 increases accordingly.
The tape-shaped insecticidal mat 34 is heated at the optimum volatilization temperature to efficiently volatilize a large amount of insecticidal components.

Further, when using the tape-shaped insecticidal mat 34 in a narrow room, the changeover switch 26 is changed to slow down the moving speed of the tape-shaped insecticidal mat 34. As a result, as the moving speed of the tape-shaped insecticidal mat 34 becomes slower, the heat generation temperature of the heating element 7 also decreases, so that the amount of volatilization of the insecticidal component is also reduced to an amount suitable for a narrow room.

Effects of the device As detailed above, this device is capable of changing the moving speed of the tape-shaped insecticidal mat according to the size of the room in which it is used, and the heating temperature of the heating element is automatically adjusted according to the moving speed of the tape-shaped insecticidal mat. Since the exothermic temperature is adjusted and set to the optimum temperature for volatilizing the insecticidal ingredient, the exothermic temperature may be too low and the insecticidal ingredient cannot be volatilized sufficiently, or the exothermic temperature may be too high and the insecticidal ingredient decomposes, reducing its effectiveness. It is possible to eliminate the conventional problems such as a decrease in performance. What's more, with the simple operation of changing the switch on the insecticide's main body according to the size of the room, the insecticidal ingredients will be automatically volatilized according to the size of the room, so the amount of volatilization will be small and the insecticidal effect will be effective. In addition, the tape-shaped insecticidal mat is not consumed prematurely due to insufficient volatilization or too much volatilization, and since no device such as a timer is required, it can be provided at low cost.
