Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a mosquito repellent device.

``Conventional technology'' Conventional mosquito repellent equipment uses a heater to heat and vaporize a mat impregnated with a mosquito repellent, and the vaporized mosquito repellent is carried by a slight upward airflow generated by the heating of the heater, so that it is naturally dispersed. There are two known methods: one in which the mosquito repellent on a mat is vaporized and diffused using hot air.

``The problem that the invention aims to solve'' However, the former method, in which the vaporized mosquito repellent is carried on the slight updraft generated by the heating of the heater and dispersed naturally, does not allow the vaporized mosquito repellent to be placed in the corners of the room where mosquitoes prefer. The latter method, in which the mosquito repellent on the mat is vaporized and diffused using hot air, has the disadvantage that it is difficult to control the vaporization rate of the mosquito repellent. was.

In addition, if both of the above conventional methods are used indoors or outdoors with windows open, the vaporized mosquito repellent will be spread to unnecessary areas.
It has the disadvantage that it may not be effective in areas where people are present.

Therefore, the present invention was developed in view of the above, and utilizes the conventional vaporization control of mosquito repellent using a heater, and can further limit and diffuse the vaporized mosquito repellent only within a desired area. The purpose is to provide mosquito repellent equipment.

"Means for Solving the Problems" In line with the above-mentioned purpose, the structure of the present invention, which is summarized in the above-mentioned utility model registration claims, includes an inner cylinder 10a and an outer cylinder 10b in order to solve the above-mentioned problems. The main body 10 has a double morning glory shape, and the bottom of the outer cylinder 10b has an intake port 1, and the main body 1
An exhaust port 2 is provided at the tip of the large diameter side of the cylinder 0, and a motor 3 is provided between the bottom surfaces of the inner cylinder 10a and the outer cylinder 10b, and the outside air sucked from the intake port 1 driven by the motor 3 is connected to the inside. Cylinder 10
A blower fan 4 that passes through between the inner tube 10a and the outer tube 10b and blows air from the exhaust port 2 is housed therein, and a mosquito-repelling side impregnated mat 22 is heated by a heater 21 on the bottom of the inner tube 10a to remove mosquitoes. A technical measure is taken in which a mosquito repellent side vaporizer 20 is arranged to vaporize the repellent.

"Embodiments" Next, embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 10 is the main body.

This main body 10 is formed into a double morning glory shape by an inner cylinder 10a and an outer cylinder 10b.

When this main body 10 is formed into a double morning glory shape by an inner cylinder 10a and an outer cylinder 10b, the inner cylinder 10a and the outer cylinder 10b are
the inner cylinder lea and the outer cylinder 10 with a desired gap between them.
Since the large-diameter end of the inner tube 10a and the outer tube 10b are integrally connected with each other leaving the exhaust port 2 described later, it is of course possible to place a partial connecting plate at an appropriate location between the inner cylinder 10a and the outer cylinder 10b, although this is omitted in the figure. It is.

Then, an intake port 1 is provided on the bottom surface of the outer cylinder 10b, and a main body 1 is provided.
An exhaust port 2 is provided at the tip of the large diameter side.

The intake port 1 may be formed by drilling one or more appropriately shaped holes in the bottom surface of the outer cylinder 10b, but the exhaust port 2 may be formed by opening one or more holes of an appropriate shape in the bottom surface of the outer cylinder 10b.
It is preferable to make the entire circumference of the large-diameter side tip an opening, or to arrange a plurality of appropriately shaped exhaust ports 2 at predetermined intervals around the large-diameter side tip.

A motor 3 is provided between the bottom surfaces of the inner cylinder 10a and the outer cylinder 10b, and a motor 3 is provided to allow outside air, which is driven by the motor 3 and sucked from the intake port 1, to pass between the inner cylinder 10a and the outer cylinder 10b. It houses a fan 4 for blowing air from the exhaust port 2.

Although not clearly shown in the figure, the blower fan 4 is a conventional centrifugal blower fan that takes in air from the center connected to the drive shaft of the motor 3 and sends air in the centrifugal direction of the radial blades. However, a propeller-type fan may be used as long as it draws outside air from the intake port 1, passes between the inner tube 10a and the outer tube 10b, and blows it from the exhaust port 2. Of course.

Furthermore, a mosquito repellent vaporizer 20 is disposed on the bottom surface of the inner cylinder 10a, which heats the mosquito repellent side impregnated mat 22 with a heater 21 to vaporize the mosquito repellent.

As the mosquito repellent vaporizer 20, a conventionally known device that can maintain the heat generated by the heater 21 at a constant temperature may be used.

In addition, in the illustrated example, this mosquito repellent vaporizer 20 is
Although the heater 21 is placed on the bottom surface of the inner cylinder 10,
There is no problem even if it is buried in the bottom of a.

The power supply circuit for the motor 3 and the heater 21 is not shown in the drawings, but it is sufficient to connect the power from a battery or an outlet after rectifying and transforming the voltage as necessary. Of course, a fuse or the like may be used.

In addition, 30 in the figure is a fitting lid that fits into the main body 10, and engagement arms 31, 31 that engage with the large diameter side tip of the main body 10 are provided on the periphery.
．． 31 .

Further, reference numeral 40 denotes a leg piece for installing the main body 10 at a desired position and at a desired inclination angle.

"Effect of the invention" Since the present invention has the above-mentioned configuration, when the motor 3 and the heater 21 are energized and the mosquito-repelling side impregnated mat 22 is placed on the heater 21, the mosquito-repelling side Impregnated mat 2
The mosquito repellent impregnated in 2 is vaporized and filled in the inner cylinder 10a, and furthermore, the vaporized mosquito repellent rides on the air from the exhaust port 2 and flows out from the inner cylinder lea.

At this time, the wind speed is high up to a predetermined distance from the main body 10, and the airflow occurs in a conical shape, and the vaporized mosquito repellent is inside this conical airflow, so the mosquito repellent is spread within a certain range. It is highly effective for mosquito control only when used outdoors or in large areas where people can enter.

In addition, at a location that is more than a predetermined distance away from the main body 10, the speed of the airflow blown from the exhaust port 2 slows down and turbulence occurs in the airflow, so the mosquito repellent is dispersed in all directions. Because it flows along with the removal agent, in a small room,
It is possible to spread mosquito repellent to every distance.
