Description

  The present invention relates to a deodorizing apparatus having a pest capturing function.

There are various causes of bad odors that occur in daily life. When consumers become sensitive to odors as in recent years, they often have a sense of disgust even with weak odors.
For this reason, various deodorants have been developed and put into practical use, and are indispensable for daily life.
In addition, conventional deodorants include adsorbents that deodorize by adsorbing odors using activated carbon, etc., chemical deodorants that deodorize by decomposing odors chemically, and deodorizing odors by masking with various fragrances. There are fragrances that can be used easily, so the diffusion rate in ordinary households is also high.
However, these deodorants and fragrances do not last for a long period of time, so it is necessary to replace the adsorbents and fragrances regularly or to spray chemical deodorants repeatedly, which is troublesome and expensive. There are problems such as this.

Therefore, in recent years, development of products that can achieve effects such as deodorization, antifouling, and antifungal using a photocatalyst has been carried out (for example, Patent Document 1).
Photocatalysts can produce effects such as deodorization, antifouling, and mold prevention by decomposing organic harmful substances that cause odors and dirt by using ultraviolet rays contained in sunlight and light from fluorescent lamps as energy. Because it has a deodorizing effect that lasts for a long time, it is used in building materials, interior materials, and sanitary facilities that cannot be easily replaced.
For example, when a photocatalyst is used for indoor wallpaper with high airtightness, the photocatalyst is activated by ultraviolet rays emitted from lighting such as a fluorescent lamp, and emitted from indoor tobacco odor (acedaldehyde), new building materials, etc. Decomposing and deodorizing harmful substances (formaldehyde) that cause sick house syndrome, and deodorizing ammonia by using it in sanitary appliances installed in toilets and nursing care facilities. There are infinite ways to use it, such as obtaining an antifungal effect.

On the other hand, the present applicant has previously proposed a “pest trap” in Utility Model Registration No. 3139542.
This pest trap is designed to suck the pests attracted by the light source with an electric fan that is combined with air and capture the pests in a breathable pest bag provided detachably below the suction means. Even if the air that has passed through the collection bag contains mites or other bacteria that are parasitic on pests, or the scales that have been peeled off from pests such as spiders are mixed, the air that has passed through the collection bag is Since it is not discharged outside the body, it can be used mainly in facilities that handle food, and it has a unique effect that even users with allergies and other diseases can be used with peace of mind. is doing.
JP 2008-79907 A

The deodorizing apparatus described in Patent Document 1 has a configuration in which a deodorizing body containing a photocatalyst and a light source for irradiating light to the deodorizing body are housed in a housing made of a resin in which a fluorescent dye is kneaded. In addition, it has an effect that the deodorizing treatment can be performed with high efficiency by the photocatalytic reaction.
However, since the deodorization apparatus described in Patent Document 1 is specialized in deodorization and does not have a function of capturing pests, it is necessary to install a pest trap separately when capturing pests, which is expensive. There are problems such as swelling.

On the other hand, the pest trap of utility model registration No. 3139542 is effective in capturing pests efficiently, but is not operated in winter when there are few pests, so the period of use is limited. There is a problem.
In addition, since there is no deodorizing function even if there is an effect of capturing pests, it is necessary to install a deodorizing device separately when it is desired to deodorize bad odors.
The present invention has been made to ameliorate such problems, and an object of the present invention is to provide a deodorizing apparatus having a pest capturing function and capable of maintaining a deodorizing effect for a long period of time.

  The deodorizing apparatus of the present invention includes an upper case in which a light source that generates ultraviolet light that attracts pests and activates a photocatalyst is attached to a lower surface, a lower case provided below the upper case, An air intake opening between the case and the air intake that is installed around the light source and activated by the ultraviolet rays irradiated from the light source, and organic harmful in the air taken in from the air intake opening Deodorizing means having a photocatalyst layer that decomposes and deodorizes the substance is provided in a plurality of stages with intervals in the vertical direction, air installed in the lower case and deodorized and purified, In the air exhausted from the suction means, which is detachably attached to the lower part of the cylindrical case connected to the lower part of the suction means, and suction means comprising an electric fan that sucks the pests attracted by the light source together with air And allergens such as pollen and dust, which is constituted from insect bag having air permeability to capture pests.

With the above structure, the photocatalyst layer is activated by irradiating the photocatalyst layer with ultraviolet light generated from a light source provided in the vicinity of the deodorant body, and the organic matter that causes odor in the air taken in from the air intake port Because the photocatalyst layer in which harmful substances are activated is decomposed into carbon dioxide and water and released into the air, it is possible to efficiently deodorize bad odors in the air and to filter the trapping net formed by non-woven fabric etc. Thus, allergens such as pollen and dust in the air can be removed, so that an air cleaning effect can be obtained by always operating.
In addition, when used as a pest trap, the pests sucked together with the air by the suction means are discharged into the catch bag through the cylindrical case and captured, thus efficiently capturing the pests attracted by the light source Since a single light source can activate the photocatalyst layer and attract pests, there is no need to provide a separate light source for deodorization and a pest light source. In addition, the cost of the apparatus can be reduced by reducing the number of parts.
Furthermore, since it has a deodorizing function and a pest capturing function, and these can be used alone or at the same time, the pest capturing function and the deodorizing function are used at the same time during the generation of the pest, so that there is little occurrence of pests. It is economical because it is not necessary to have both a deodorizing device and a pest trap, since it can be used throughout the year by using the deodorizing function alone.

  The deodorizing apparatus of the present invention coats a deodorizing body on at least a surface of an annular substrate having a circular hole having a circular hole in the center and having a tapered surface that gradually decreases from the outer peripheral edge side to the circular hole side. And a light source is installed at substantially the center of the circular hole.

  Due to the above structure, the photocatalyst layer is always activated by being irradiated with ultraviolet rays from a light source provided at a short distance from the deodorant body, so that it can be used from animal odors such as acedaldehyde and pets that cause tobacco odor, garbage, etc. Due to the deodorizing effect such as the released ammonia odor and the antibacterial action such as antiviral and antifungal, the effect of preventing the growth of bacteria can be obtained for a long time.

  The deodorizing apparatus of this invention forms a photocatalyst layer by coating an apatite titanium dioxide coating agent.

  With the above configuration, even if the photocatalyst layer needs a certain amount of time to decompose the organic harmful substance, the apatite captures the organic harmful substance and does not let it escape, so the organic catalytic substance can be reliably decomposed by the photocatalytic layer. At the same time, when the photocatalyst layer decomposes the organic harmful substance, the apatite forms a system for adsorbing the organic harmful substance again and repeats the adsorption and decomposition, so that the deodorizing effect can be maintained for a long time.

  The deodorizing apparatus of the present invention is a device in which when a photocatalytic layer is formed on an annular substrate, a protective layer is formed by coating acrylic acid as a base on the annular substrate, and an apatite titanium dioxide coating agent is coated on the protective layer. is there.

  With the above structure, the protective layer coated on the annular substrate diffuses and reflects the ultraviolet rays that have passed through the photocatalyst layer, and the photocatalyst layer is further activated by returning the ultraviolet rays to the photocatalyst side again. It will be obtained.

According to the deodorization apparatus of the present invention, the photocatalyst layer is activated by irradiating the photocatalyst layer with ultraviolet rays generated from a light source provided in the vicinity of the deodorizer, and the air in the air taken in from the air intake port is activated. The organic toxic substances that cause odors are decomposed into carbon dioxide and water by the activated photocatalyst layer and released into the air, so that bad odors in the air can be efficiently deodorized and formed with a nonwoven fabric, etc. Since the allergic substances such as pollen and dust in the air can be removed by the filter effect of the trapping net, the air purifying effect can be obtained by always operating.
In addition, since the deodorization function and the pest capture function can be used alone or simultaneously, the pest capture function and the deodorization function are used at the same time when the pests are generated, and the deodorization function is used when the pests are rarely generated. It is economical because it can be used throughout the year and it is not necessary to have both a deodorizing device and a pest trap.

Embodiments of the present invention will be described in detail with reference to the drawings.
1 is a front view of the deodorizing apparatus, FIG. 2 is a sectional view taken along the line AA in FIG. 1, FIG. 3 is a partially cutaway perspective view near the suction means, and FIG. 4 is an enlarged sectional view of the deodorizing means. 5 to 7 are explanatory diagrams of the operation.
1 includes an upper case 2 and a lower case 3, an air intake 4 provided between the upper case 2 and the lower case 3, and a lower case 3. The entire apparatus body 1 has a compact cylindrical shape that is long in the vertical direction.
The upper case 2 includes an upper case 2a and a lower case 2b, and the upper case 2a and the lower case 2b are fixed by a fixing tool 2f such as a screw in a state where the upper case 2a is fitted to the lower case 2b from above. In addition, an annular hanger 9 for suspending the apparatus main body 1 is provided at the center of the upper case 2a.

A cord lead-in port 2c is formed at a position slightly deviated from the center of the upper case 2a, and one end side of the power cord 10 is drawn from the cord lead-in port 2c, and a power switch is placed in the middle of the power cord 10. On the other end side, a plug (not shown) for connection to a commercial power source is provided.
One end side of the power cord 10 drawn into the upper case 2 from the cord lead-in port 2c is branched into two paths in the upper case 2, and one side 10a is connected to the light source 12 installed on the lower surface of the upper case 2 and the other side 10b. Is routed in the lower case 3 through a hollow column 13b of the guide means 13 (described later) provided in the air intake 4 and connected to the electric motor 5b of the suction means 5 provided in the lower case 3. ing.

On the bottom surface of the bottom plate 2d of the lower case 2b, a socket 12a is fixed substantially at the center, and a light bulb type light source 12 is detachably attached to the socket 12a.
The light source 12 is a fluorescent lamp that activates the photocatalyst and emits ultraviolet light having a wavelength of a light wavelength component at a wavelength preferred by a pest, for example, 300 to 400 nm. In addition, it is possible to easily replace the light source 12 by removing the upper case 2.
The lower case 3 is formed of a cylindrical body having an outer diameter substantially equal to the outer diameter of the upper case 2, and an annular support plate 3 a is provided inside slightly below the upper end.
The air intake 4 provided between the upper case 2 and the lower case 3 is for a pest attracted by the light source 12 to enter the apparatus main body 1. A deodorizing means 13 having a deodorizing function for deodorizing malodors, which is a main part of the present invention, is provided with a smooth guiding function and a guard function for preventing the hand or the like from directly touching the light source 12. It has been.

As shown in FIG. 2, the deodorizing means 13 includes a plurality of support columns 13b made of, for example, metal pipes or resin pipes, and a plurality of deodorant bodies 13a inserted into the support columns 13b.
The upper end portion of each column 13b is fixed to the bottom plate 2d by a nut 13c while passing through the bottom plate 2d of the lower case 2b, and the lower end of each column 13b is screwed to the column plate 3a of the lower case 3.
The columns 13b are arranged at substantially equal intervals in the circumferential direction of the apparatus body 1, and a plurality of mounting holes 13d drilled in the deodorant body 13a are fitted into the columns 13b.
As shown in FIG. 2, each deodorant body 13a has an annular substrate 13f having a circular hole 13e in the center and a tapered surface inclined so as to be sequentially lowered from the outer peripheral edge side to the circular hole 13e, and the annular substrate 13f. It consists of 13g of photocatalyst layers coated on the surface.
The annular substrate 13f is integrally formed of, for example, ABS resin, and is fitted to each column 13b at almost equal intervals. The intervals between the annular substrates 13f are such that a child's finger cannot enter and the ring substrate 13f is It is set to the extent that relatively large pests can enter.

The photocatalyst layer 13g is activated in the vicinity of 350 nm of the wavelength of ultraviolet rays irradiated from the light source 12, and titanium dioxide having the ability to decompose organic harmful substances most efficiently is used.
In contrast, pests have the property of being attracted to light having a light wavelength component peak at 300 to 400 nm.
That is, by using a fluorescent lamp that generates light having a light wavelength component peak at 300 to 400 nm as the light source 12, the photocatalytic layer 13g formed on the surface of the annular substrate 13f is activated, and organic harmful substances are removed. While being able to decompose efficiently, pests can be attracted into the upper case 2 from the air intake 4, and a single light source 12 can be used as both a deodorizing light source and a pest-inducing light source. become able to.

Moreover, the photocatalyst layer 13g which forms the deodorant body 13a uses the titanium dioxide which produced the apatite on the surface.
It is known that titanium dioxide has the ability to decompose and detoxify organic harmful substances by photocatalysis when irradiated with ultraviolet rays.
However, since it does not have the ability to actively adsorb bacteria, it can only be sterilized and decomposed by bacteria in contact with the surface.

Apatite, on the other hand, has the ability to adsorb bacteria because it has the ability to adsorb proteins, but it cannot dissociate protein substances once adsorbed, so the substance remains attached forever and sterilizes over time. The effect is reduced.
Therefore, in order to utilize the advantages of both and eliminate the disadvantages, apatite titanium dioxide in which both are combined is used as a photocatalyst.
In an embodiment of the present invention, an “apatite titanium dioxide coating agent (trade name: nu-COAT AP) developed by an independent administrative agency“ National Institute of Advanced Industrial Science and Technology ”(Japanese Patent No. 3275032) and commercialized by Neutral Corporation. Is used.

  This apatite titanium dioxide coating agent has a feature that the photocatalytic layer 13g can be formed by one coating. However, when the annular substrate 13f to be coated is, for example, an ABS resin, the surface of the annular substrate 13f may be roughened. A protective layer (not shown) is preliminarily formed on the surface of the annular substrate 13f by gun blowing as a base, and an apatite titanium dioxide coating agent is coated thereon by gun blowing to form a thin film photocatalyst. It has a two-layer structure in which the layer 13g is formed.

The suction means 5 installed in the lower case 3 is provided with a fan 5c rotated by an electric motor 5b in a casing 5a, and the upper surface of the casing 5a is fixed to the lower surface of the support plate 3a of the lower case 3. The pests attracted by the light source 12 and invaded through the air intake 4 are sucked into the cylindrical case 6a of the shutter means 6 provided below the suction means 5 by the fan 5c rotated by the electric motor 5b. It is like that.
The shutter means 6 includes a cylindrical case 6 a and a shutter plate 6 b provided in the cylindrical case 6 a, and the upper end portion of the cylindrical case 6 a is connected to the lower surface of the casing 5 a of the suction means 5.

As shown in FIG. 3, the shutter plate 6b of the shutter means 6 is made of a disc having a diameter slightly smaller than the inner diameter of the cylindrical case 6a, and is formed in a thin plate shape by a light material such as plastic, and from the center. The eccentric position is fixed to the rotating shaft 6c.
Both ends of the rotating shaft 6c are supported by the cylindrical case 6a so as to be horizontal, and a shutter plate 6b is rotatable about the rotating shaft 6c. A shutter plate is provided at both ends of the rotating shaft 6c. A spherical spacer 6d that forms a minute gap therebetween is fitted so that the outer peripheral edge of 6b does not contact the inner peripheral surface of the cylindrical case 6a.

The shutter plate 6b is provided with a balancer 6e on the eccentric side.
The balancer 6e returns the shutter plate 6b whose eccentric position is supported by the rotating shaft 6c to the horizontal position. The shutter plate 6b is automatically operated when the suction means 5 is stopped and the inside of the cylindrical case 6a becomes no wind. The stopper 6f protrudes on the inner peripheral surface of the cylindrical case 6a to stop the shutter plate 6b in contact with the shutter plate 6b at the horizontal position.
The cylindrical case 6a of the shutter means 6 is provided with a locking portion 6g projecting on the outer periphery of the lower portion, and the opening 15a of the insect repellent bag 15 is locked to the locking portion 6g.

As shown in FIG. 4, the locking portion 6 g is composed of a protrusion protruding from the outer peripheral surface of the cylindrical case 6 a, a not-shown concave groove, and the like, and a rubber band inserted in advance through the opening 15 a of the insect bag 15. The opening 15a is locked by the locking means 15b such as the above so that the insect bag 15 does not fall off even if the suction means 5 receives wind pressure in the insect bag 15.
The insect pouch 15 is formed into a bag shape from a breathable material such as a fine mesh or a non-woven fabric that does not allow small pests to pass through, and can be disposed of together with the captured pests.

On the other hand, a bellows-like cover 16 is attached to the lower part of the lower case 3.
This cover 16 covers the periphery of the pest bag 15 so that the pests captured in the pouch 15 cannot be seen from the outside. The cover 16 is formed of a soft resin so as to have the same diameter as the lower case 3 and extends. In this case, the length is set so that the lower part of the insect bag 15 cannot be seen.
When replacing the insect bag 15, the insect bag 15 can be easily replaced by contracting as shown in FIG. 7.

Next, the operation of the deodorizing apparatus constructed as described above will be described. The apparatus body 1 has a deodorizing function and a pest capturing function, the deodorizing function is independent, and the pest capturing function and the deodorizing function are simultaneously performed. Although it can be used, the deodorizing action and the insect capturing action will be explained separately.
If you want to use only the deodorizing function in winter when there is little occurrence of pests, suspend the device body 1 from the place where you want to deodorize. By attaching, allergen-causing substances such as pollen and dust can be filtered by the insect trap bag 15, so that it is also great for allergy countermeasures such as hay fever.
When the apparatus main body 1 is installed in a place where it is desired to deodorize and the switch is turned on, the light source 12 is turned on, and at the same time, the electric motor 5b of the suction means 5 is rotated to start blowing air by the fan 5c.

When the fan 5c is rotated by the electric motor 5b, the air around the light source 12 is sucked into the lower case 3 by the suction means 5, so that outside air is sucked into the upper case 2 from the air intake port 4.
The air intake 4 is provided with a plurality of deodorizing bodies 13a inclined downward in the vertical direction at substantially equal intervals, and the air sucked into the air intake 4 is directed downward by the guide action of these deodorizing bodies 13a. Therefore, the suction means 5 having a small suction capacity can efficiently take in the outside air around the air intake 4 and the air sucked into the air intake 4 is rectified by the deodorant body 13a. While being accelerated by the action, it flows between the deodorant bodies 13a as shown by the arrow B in FIG. 4, and at this time, the organic harmful substance D which is an odor component contained in the air is formed on the surface of the deodorant body 13a. It contacts the formed photocatalyst layer 13g.

Since the photocatalyst layer 13g is formed of an apatite titanium dioxide coating agent and the surface of titanium dioxide is coated with apatite, the organic harmful substance D is adsorbed by the apatite and accumulated on the surface of the photocatalyst layer 13g.
When the photocatalyst layer 13g formed on the surface of the deodorizing body 13a is irradiated with ultraviolet C contained in the light generated from the light source 12 from a short distance, the photocatalyst layer 13g is activated and accumulated on the surface of the photocatalyst layer 13g. The organic harmful substance D is decomposed into carbon dioxide (CO ₂ ) and water (H ₂ O) as shown in FIG. 5 and released into the air sucked by the suction means 5, but the photocatalytic layer 13g. Requires a certain amount of time to decompose the organic harmful substance D.

However, since the apatite captures the organic harmful substance D and does not escape it, the photocatalytic layer 13g can reliably decompose the organic harmful substance.
This removes organic toxic substances such as ammonia odor which causes malodor, acetaldehyde which causes tobacco odor, formaldehyde which causes sick house syndrome, and mold odor.
Further, the protective layer coated on the surface of the annular substrate 13f as a base of the photocatalyst layer 13g diffuses and reflects the ultraviolet C transmitted through the photocatalyst layer 13g, and returns the ultraviolet C to the photocatalyst 13g again, thereby further activating the photocatalyst layer 13g. Therefore, a higher deodorizing effect can be obtained.

  On the other hand, when the shutter means 6 installed below the suction means 5 receives the wind pressure of air blown by the fan 5c (arrow B in FIG. 6) to the shutter plate 6b that has been closed by the action of the balancer 6e until now, Since the rotating shaft 6c rotates about 90 degrees and is opened, allergenic substances such as pollen and dust sucked together with air by the suction means 5 pass through the cylindrical case 6a and enter the insect trap bag 15. The allergen is filtered by the insect trapping bag 15 formed of a net or nonwoven fabric, and the air passes through the insect trapping bag 15 as shown by an arrow E in FIG. More indoors will be discharged.

Due to the titanium dioxide photocatalytic reaction by the photocatalyst layer 13g formed on the deodorant body 13a, harmful substances such as formaldehyde released from exhaust gas (NOx, SO _x ) new building materials, acedaldehyde causing tobacco odor, Bacterial growth prevention effect can be obtained by deodorizing effect such as animal odor such as pet, ammonia odor released from garbage etc. and antibacterial action such as antiviral and antifungal.
Further, the filter effect of the insect trap 15 allows the removal of allergens such as pollen and dust in the air, and the suction means 5 is always rotated to circulate the air, thereby obtaining an air cleaning effect.

The case where deodorization is performed using the apparatus main body 1 has been described above. Next, the operation when a pest is captured will be described.
Installation locations for capturing pests include indoor spaces in general households, food processing plants, restaurants, convenience stores and other food and products where pests are difficult to mix, and places where people are uncomfortable. It is suitable for general households, restaurants, convenience stores, etc. with limited installation space, but there are no restrictions on the installation location and the outdoors. Of course, it may be installed in a facility such as a plastic house.
When the apparatus main body 1 is installed indoors, the upper case is arranged so that the light source 12 provided on the upper part of the apparatus main body 1 is in the vicinity of the ceiling so that pests gathering on the lighting apparatus installed on the ceiling can be efficiently captured. The apparatus main body 1 is suspended from the ceiling or the like by means of a lifting tool 9 provided at 2.

When the attachment of the apparatus main body 1 is completed, the bellows-like cover 16 attached to the lower part of the lower case 3 is contracted to the position shown in FIG. 7, and the opening 15a of the insect trap 15 prepared in advance is placed at the lower end of the cylindrical case 6a. It is fitted to the outer periphery, and the outer periphery of the opening 15a is locked to the locking portion 6g protruding from the outer peripheral surface of the cylindrical case 6a by the locking means 15b such as a rubber ring. Can be prevented from slipping down even if the insect acts downward from the inside of the insect trap bag 15.
When the attachment of the insect trap 15 is completed, the cover 16 is extended to the original position, and then the power switch provided in the middle of the power cord 10 is turned on. Then, the light source 12 is turned on and simultaneously the electric motor 5b of the suction means 5 is turned on. Rotates, and blowing by the fan 5c is started.

When the fan 5c is rotated by the electric motor 5b, the air around the light source 12 is sucked into the lower case 3 by the suction means 5, so that air near the ceiling is sucked from the air intake port 4.
The air intake 4 is provided with a plurality of deodorizing bodies 13a inclined downward in the vertical direction at substantially equal intervals, and the air sucked into the air intake 4 is directed downward by the guide action of these deodorizing bodies 13a. Since the flow is rectified in the direction, the suction means 5 having a small suction capacity can efficiently take in the outside air around the air intake 4 and the air sucked into the air intake 4 is rectified by the guide plate 13a. Since the speed is increased by the action and sucked into the suction means 5, the air around the light source 12 can be sucked almost uniformly.

  In addition, since the light source 12 uses a light bulb such as a fluorescent lamp that generates an attracting light having a wavelength preferred by a pest, a pest that is attracted by a lighting fixture installed indoors and enters the indoor space also enters the light source 12. When attracted and reaches the vicinity of the light source 12, the air is sucked into the suction means 5 together with the air sucked into the air intake 4.

  On the other hand, when the shutter means 6 installed below the suction means 5 receives the wind pressure of air blown by the fan 5c (arrow B in FIG. 6) to the shutter plate 6b that has been closed by the action of the balancer 6e until now, Since it is opened by rotating about 90 degrees around the rotating shaft 6c, the pests sucked together with air by the suction means 5 are discharged into the insect trap bag 15 through the cylindrical case 6a. Since only insect pests are captured in the insect trap bag 15 formed of a net or nonwoven fabric, and the air passes through the trap bag 15 as shown by arrow E in FIG. The pests attracted by the light source 12 can be efficiently captured in the insect trap bag 15.

Further, the air sucked into the air intake 4 is circulated between the deodorant bodies 13a as shown by an arrow B in FIG. 4 while being accelerated by the rectifying action of the deodorant body 13a. When the organic toxic substance which is an odor component contained in the gas comes into contact with the photocatalyst layer 13g formed on the surface of the deodorant body 13a, it is decomposed into carbon dioxide (CO ₂ ) and water (H ₂ O) by the deodorizing function. Then, since it is released into the air sucked by the suction means 5, a deodorizing effect can be obtained even when capturing pests.

If a certain amount of pests accumulates in the catching bag 15 during the long-time operation, the pests captured in the catching bag 15 are discarded together with the catching bag 15. When the suction means 5 is turned off, the air blowing by the suction means 5 is stopped, and the shutter plate 6b, which has been in the open position until now by the wind pressure, is rotated to the horizontal position by the action of the balancer 6e, and the upper surface of the cylindrical case 6a The opening is closed by the shutter plate 6b.
As a result, even if some of the pests captured in the insect trap bag 15 are alive, the shutter plate 6b prevents the insect pests from escaping to the suction means 5 side that has stopped suctioning by being turned off. It is possible to reliably prevent the living pests from escaping from the insect trap bag 15.

When the light source 12 is turned off and the suction means 5 is completely stopped, the cover 16 is contracted to the position shown in FIG. 7 to expose the insect capturing bag 15, and the tube 15 is manually squeezed while the aperture 15a of the insect capturing bag 15 is squeezed. By removing the insect trapping bag 15 from the lower part of the shaped case 6a and discarding it with the locking means 15b closing the opening 15a of the insect trapping bag 15, the entire insect trapping bag 15 can be discarded without escaping the captured insect pest. it can.
When a new insect trap 15 is attached to the lower part of the cylindrical case 6a, the cover 16 can be extended to the position shown in FIG. become.

In the above embodiment, the case where the photocatalyst layer 13g is formed only on the surface of the annular substrate 13f has been described. However, the photocatalyst layer 13g may be formed also on the back surface side of the annular substrate 13f.
The photocatalyst layer 13g was formed by coating an annular substrate 13f with an apatite titanium dioxide coating agent, and activated by irradiating ultraviolet light having a peak of the light wavelength component at a wavelength preferred by pests, for example, 300 to 400 nm. If it is a photocatalyst, it will not specifically limit to this.
Furthermore, although the cover 16 is formed in a bellows shape, a similar effect can be obtained by providing a cylindrical cover that can slide up and down along the outer peripheral surface of the lower case 3, and when used only as a deodorizing device. The cover 16 may be omitted.
Further, although an example in which a power switch is provided in the middle of the power cord 10 has been described, it is needless to say that a power switch may be provided in a part of the apparatus body 1, for example, the lower case 3.
