Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a pest control device for effectively controlling pests such as mites.

(b) Conventional technology In the past, for example, house dust mites breed in the nests of mice and develop by parasitizing blood sucking in rats, but when they become numerous, they may crawl outside the nests, sucking humans and causing skin rashes. . However, recently, there are many cases in which dust mites, clawed mites, etc. abnormally propagate in tatami mats and carpets even without mouse nests, which may induce asthma and allergies, which has become a social problem.

In the past, insecticides have been sprayed to control pests such as mites, and smoke has been used to control insecticides according to their pharmacological effects. Other methods that do not use insecticides include a method of sucking with a suction cleaner and a method of killing harmful insects by radiant heat treatment with far infrared rays.

(c) Problems to be solved by the invention However, such insecticides may have a bad effect on the human body, especially infants, and should be insecticides with low toxicity to humans and pets. However, in general, the less toxic insecticide has a lower insecticidal effect, and there is a problem in that it cannot achieve the purpose of sufficient pest control. The method using a suction cleaner can be captured by making the eyes of the dust-collecting paper pack fine, but in many cases it does not die. Further, the radiant heat treatment method using far infrared rays requires a high-power heater to generate far infrared rays, and the heater portion near the surface of the tatami mat or the carpet becomes hot, which may cause smoking or ignition.

An object of this invention is to provide a pest control device capable of controlling pests efficiently and safely.

(d) Means for Solving the Problems The pest control device of the present invention is a metal plate partially exposed at the bottom and heats the metal plate to the insecticidal effect temperature of the target pest by contacting the metal plate. It is characterized by comprising a nozzle case provided with a heating plate made of a heating element, and a suction cleaner connected to the nozzle case and sucking dead pests from the nozzles of the nozzle case.

(e) Action In general, pests are vulnerable to high-temperature environments, and for example, mites are reported to be 100% dead when exposed to temperatures of 40 ° C. or higher, according to the summary of case study meetings of the Society for Antibacterial and Antifungal Society of Japan. Therefore, when the ticks are removed, by heating the metal plate to about 40 ° C. by the heating element, when the nozzle case is moved along the surface of the tatami mat or the carpet, the part of the tatami mat or the carpet in contact with the heating plate is removed. About 40 ° C inhabiting mites
It is heated up to die. Dead mites are sucked and removed by a suction cleaner connected to the nozzle case.

(f) Example FIG. 1 shows a cross section of the main part of the pest control device according to an example of the present invention. Further, a top view of a part of the parts shown in FIG. 1 is shown in FIG. In FIG. 1, 10 is a nozzle case attached to the tip of a pipe joint of a suction cleaner, 4 is a case body, and 6 is a pipe joint. This pipe joint 6 is connected to a pipe joint 7 on the suction cleaner side. Reference numeral 2 denotes a metal plate exposed on the bottom surface of the nozzle case, and an opening 3 is formed on a part of the bottom surface. A part 2a of the metal plate 2 is a case body 4
One of the separated rooms 8
Inside, the heating element 1 made of a positive temperature coefficient thermistor is bonded to the surface of the metal plate 2a. The combination of the heating element 1 and the metal plate 2 constitutes the heating plate according to the present invention.

FIG. 2 is a top view showing the joined state of the metal plate 2 and the heating element 1 joined to a part thereof (the case body 4 is not shown).
The heating element 1 heats the entire exposed portion of the bottom surface to about 40 ° C. via the metal plate 2a.

The nozzle case is configured as described above, and the surface portion of the carpet that is in contact with the metal plate 2 is heated to about 40 ° C. by sucking it along the surface of the carpet 11 with the suction cleaner. Pests can be killed by heat. Dead pests such as mites are immediately sucked from the opening 3 through the suction chamber 5 and the pipe joints 6 and 7 to the suction cleaner, and are collected by the dust collector in the suction cleaner.

The heating element is not limited to the positive temperature coefficient thermistor, but by using the positive temperature coefficient thermistor, the automatic temperature control function can be effectively used, and abnormal overheating or the like does not occur. Further, by providing the attachment location of the heating element outside the flow path of dead insects and other harmful insects and dust, it is possible to prevent the harmful effects of the dead insects and dust from adhering.

In the examples, a metal plate partially having a heating element attached was used as the heating plate. However, a metal plate having a heat pipe embedded therein may be used instead of the metal plate, or an organic heater or a sheath heater may be used on the entire metal plate. It is also possible to embed a ribbon heater, etc. Furthermore, it is possible to prevent the damage to the heated object by implanting bristles having high thermal conductivity on the surface of the heating plate exposed on the bottom surface of the nozzle case.

(g) Effect of the Invention According to the invention as described above, the heating plate is brought into direct contact with the object to be heated such as tatami mat or carpate, so that the temperature of the heating plate is kept to the minimum necessary temperature. This is sufficient and the pests can be killed without damaging the object to be heated. Since the dead pests are immediately sucked by the suction cleaner, the heated object can be kept clean. Further, when the apparatus is used, the object to be heated is dried, and other dust is floated, so that the suction effect is improved.
