Description

[Detailed Description of the Invention] The present invention relates to a fumigation device that exterminates pests by heating a fumigation mat impregnated with a heat-volatilizing agent to exterminate cockroaches, mosquitoes, and other pests.

Conventional fumigation equipment generally heats one fumigation mat with one heater to perform fumigation, but if the room in which the fumigation equipment is installed is large, pests There was a problem in that the vapor concentration of the pesticide was insufficient and its ability to kill pests was insufficient.

In addition, one way to eliminate this drawback is to make one fumigation mat in several sizes depending on the size of the room, but users of this fumigation equipment must purchase several types of fumigation mats. There was a problem.

This invention was proposed in view of the above problems,
The aim is to provide a fumigation device that can spray an appropriate amount of pest control agent depending on the volume of the room to be evaporated.

The present invention will be explained in detail below.

In FIGS. 1 to 3, a cylindrical body 1 has upper and lower air circulation portions, and a wire mesh fumigation mat mounting plate 2 is attached near the middle of the cylindrical body 1 to cross the cylindrical body 1.

A wire-wound heater 3 for heating the fumigation mat and improving air circulation is housed in a heater storage chamber 1a in the lower part of the cylindrical body 1 partitioned by a fumigation mat mounting plate 2.

The fumigation mat storage chamber 1b in the upper part of the cylindrical body 1 is formed to have a height more than twice the thickness of the fumigation mat, and its upper surface is open.

The cylindrical body 1 is covered with an outer cylinder 5. The carrier 4 is made of a so-called porous material and is solidified into a substantially disk shape, and is impregnated with a certain amount of a heat-volatile pest control agent to form a fumigated matzer.

For example, one fumigated Matsuro is impregnated with a pest control agent suitable for a room of 4 and a half tatami mats, and if it is used in a room of 4 and a half tatami mats, one fumigated Matsuro is used in a room of 8 tatami mats. In this case, two fumigation mats are stacked in two stages, and in case of use in a 12 tatami room, three fumigation mats are stacked in three stages and placed on the fumigation mat mounting plate 2, respectively.

The pest control agent impregnated in the fumigated maturo is evaporated by the heating of the heater 3 and spread into the air by the rising air flow generated by the heating of the heater 3.

FIG. 2 shows a different embodiment of the invention.

The disc-shaped fumigation maturo is provided with volatilization holes 7 for the purpose of increasing the evaporation surface area, and positioning notches 8 are provided at equal pitches on the circumferential body, and positioning protrusions 9 are formed on the inner wall of the inner cylinder 1. ing.

Positioning protrusion 9 when multiple fumigated Matsutoro are stacked
The fumigation mat is placed on the fumigation mat placement plate 2 with the notches 8 fitted therein.

In this embodiment, since the notch 8 and the positioning protrusion 9 are fitted and positioned, the pitch of the volatilization holes 7 of the fumigated maturo matches, and the pest control agent evaporated from the fumigated maturo on the lower stage is transferred to the upper stage. It has the effect of being able to pass through the volatilization hole 7 without being obstructed by the fumigated matsutoro.

FIG. 3 shows a further different embodiment of the present invention, in which a disc-shaped fumigating maturo is held at a point by guide protrusions 10 protruding from the cylindrical body 1 at appropriate pitches, and is moved from the cylindrical body 1 through equal gaps. When two or more stacks of fumigated pine nuts are stacked, the pest control agent can be evaporated evenly from the gaps without shifting their positions.

As described above, the fumigation device of the present invention includes a fumigation mat storage chamber with an opening at the top formed at a height more than twice the thickness of the fumigation mat impregnated with a certain volume of heat-volatile pest control agent, and a fumigation mat storage chamber with an opening on the top. Since it is equipped with a heater that heats the fumigation mat housed in the room, it is possible to spray an appropriate amount of pest control agent depending on the capacity of the room with one heater and one type of fumigation mat.
