Description

[Detailed description of the invention] Industrial applications The present invention relates to insecticides, particularly cordless insecticides.

Conventional Structure and Problems Conventionally, there are insecticides that exterminate insects, mosquitoes, flies, etc. that are harmful to the human body by evaporating insecticide into the air as a gas through a heating chamber. In such insecticides, a fibrous mat impregnated with an insecticide is placed on a heating element that generates heat using electricity, and the heat from the heating element evaporates and scatters the insecticide from the mat into a gas into the air, killing insects. There is. In order to energize the heating element, there are some types that conduct electricity from the power supply through a cord of an appropriate length, but in recent years, the case of the insecticide itself has a plug blade attached to it, and this is connected directly to the outlet. So-called cordless insecticides, which generate heat using a heating element, have become popular because they are small and lightweight and do not take up much space. A perspective view of such a conventional cordless insecticide is shown in Figure 2, and a cross-sectional view thereof is shown in Figure 3. As shown in the figure.

In Fig. 2 and Fig. 3, 1 is an insecticide case, a plug blade 3 is fixed to the side wall 2 of the case 1, and an opening in the upper horizontal surface 4 of the case 1 for evaporating and scattering the insecticide gas. 5 is a provision.

Inside the case 1, a heating element 6 is provided directly below the opening 5.
This is electrically connected to the plug blade 3. The upper surface of the heating element 6 is provided with a mat placement surface 7 on which an insecticide-impregnated mat is placed. The opening 5 is generally rectangular, and a bridge 8 is provided approximately in the center thereof parallel to the blade attachment side wall 2. This bridge 8 is provided to prevent a person's fingers or the like from touching the heating element 6 or the mat mounting surface 7 below the opening 5 and getting burned.

In the above-mentioned conventional insecticide, when the plug blade is inserted into an outlet, it is heated by the heating element, and the evaporated insecticide gas is scattered upward from the opening 5 and in all directions. For this reason, installing an outlet with a plug blade inserted has the disadvantage that gas also scatters on the wall surface, and insecticides adhere to the wall surface, gradually staining the wall surface over time.

In order to solve this problem, it is possible to increase the distance between the side wall 2 where the blade is fixed and the opening 5 to reduce the amount of the insecticide gas reaching the wall surface, but if this is done, the insecticide itself will become large and small. This is undesirable as it goes against weight reduction.

Purpose of the Invention The present invention controls the direction of evaporation and scattering of the insecticide gas in the above-mentioned conventional cordless insecticide, and prevents the insecticide gas from scattering as much as possible in the direction of the side wall 2 where the plug blade is fixed, that is, in the direction of the wall surface when the outlet is installed. The purpose is to prevent the wall surface from getting dirty.

Structure of the Invention The present invention has a heating element for heating the insecticide-impregnated mat inside the case, a plug blade on the side surface, and an insecticide evaporative gas release opening on the upper horizontal surface, and the above-mentioned gas is emitted parallel to the side surface of the case. A cordless insecticide having a bridge with a rectangular cross section located approximately at the center of the opening, the cordless insecticide having the bridge mounted so that its top surface is at an angle of 30 to 60 degrees with respect to the horizontal plane and is at an elevation angle in the direction opposite to the direction of the blade. It's in the insecticide.

DESCRIPTION OF EMBODIMENTS The insecticide of the present invention will be specifically explained below with reference to FIG.

FIG. 1 is a sectional view corresponding to FIG. 3 of the insecticide of the present invention, and all parts corresponding to the respective constituent parts shown in FIG. 3 are designated by the same numbers.

According to the present invention, as shown in the figure, the bridge 8 is at an angle (φ) of 30 to 60° with respect to the case horizontal plane 4, and in a direction opposite to the direction of the blade, that is, the direction of the blade fixing side wall 2, that is, the opposite side wall 2. It is installed so that the angle of elevation is in the direction of .

In the insecticide of the present invention having the bridge 8 configured as described above, an insecticide-impregnated mat (not shown) is placed on the mat placement surface 7, and when the insecticide is attached to an outlet, the insecticide is released from the mat. It evaporates and scatters as a gas. When this gas is illuminated from the side in a dark, windless room, it is possible to observe the state in which the gas scatters and flows. At this time, the flow of gas scattering is determined by the distance from the wall surface to the corner of the bridge 8■
It was actually measured in relation to the distance from the case horizontal plane 4 when various changes were made. Table 1 In the data in Table 1, 0crRs (for example, at a height of 10G+ from the horizontal plane) is 0clI when the angle of the bridge is 06 (i.e., horizontal) and 90' (i.e., vertical). Indicates that it is touching the wall. Therefore, in this case the possibility of stain formation on the walls is high. The larger this number is, the farther the gas is from the wall, and the less dirt is formed on the wall.

As is clear from the data in Table 1, the angle of the bridge 8 (φ
It is clear that when is between 30 and 60°, the gas flow leaves the wall and does not form dirt.

Effects of the Invention According to the present invention, the inclination angle of the bridge provided at the opening of the cordless insecticide with respect to the horizontal plane is 30 to 60 degrees, and the elevation angle is in the direction of the side wall 2'. have
