Modes for carrying out the invention

(first embodiment)

With reference to fig. 1 to 2, an air blowing device 101 according to a first embodiment of the present invention will be described. Fig. 1 is a perspective view of an external appearance of the air blower 101. Fig. 2 shows a cross-sectional view of the blower 101. The air blower 101 includes: a casing 1 having an air inlet 11 and an air outlet 12; a blower fan 5 disposed inside the casing 1; a cover member 2 which is detachably attached to the casing 1 so as to cover the inflow port 11, defines a first space 20 outside the inflow port 11, and has an air inlet 13 facing the first space 20; and a carbon dioxide generator 17 disposed outside the first space 20 or the lid member 2. In the present embodiment, the carbon dioxide generating agent 17 is disposed in the first space 20.

The carbon dioxide generator 17 may be a generator based on a known technique. For example, the carbon dioxide generating agent 17 may be in the form of a block. For example, the carbon dioxide generating agent 17 may be a powder generating agent put in a bag.

In the present embodiment, since the blower 101 includes the carbon dioxide generating agent 17 disposed in the first space 20 or outside the cover member 2, carbon dioxide can be generated. The blower 101 of the present embodiment is compact and can attract mosquitoes because of the nature of mosquitoes to be attracted by carbon dioxide gas. The blower 101 in the present embodiment is not limited to attracting mosquitoes, and may attract insects having a property of being attracted by carbon dioxide. Examples of insects having a property of being attracted to carbon dioxide include gadflies and gnats.

As shown in fig. 2, the carbon dioxide generating agent 17 is preferably disposed above the first space 20 of the lid member 2. Since carbon dioxide is heavier than air, it tends to flow downward. As shown in the present embodiment, if the carbon dioxide generating agent 17 is disposed at the upper portion in the first space 20, the carbon dioxide generated from the carbon dioxide generating agent 17 can easily diffuse throughout the first space 20.

(second embodiment)

Referring to fig. 3, an air blowing device 102 according to a second embodiment of the present invention will be described. In the blower 102, the carbon dioxide generating agent 17 is supported by the inner surface of the cover member 2. The other configurations are the same as those described in the first embodiment.

The same effects as those of the first embodiment can be obtained also in the present embodiment. In the present embodiment, since the carbon dioxide generating agent 17 is supported by the lid member 2, the carbon dioxide generating agent 17 can be removed integrally with the lid member 2 when the lid member 2 is removed from the housing 1. Therefore, in the present embodiment, maintenance of the carbon dioxide generating agent 17 is easily performed. Since the carbon dioxide generating agent is disposed on the inner surface of the cover member 2, the carbon dioxide generating agent 17 is not visible when the blower 102 is viewed from the outside, and the appearance of the blower 102 can be made neat.

(third embodiment)

Referring to fig. 4, an air blowing device 103 according to a third embodiment of the present invention will be described. In the blower 103, the carbon dioxide generating agent 17 is supported by the outer surface of the cover member 2. The other configurations are the same as those described in the first embodiment. In fig. 4, the carbon dioxide generating agent 17 is shown in a simple shape of a substantially rectangular shape, but this is only a schematic view, and the shape of the actual carbon dioxide generating agent 17 is not limited thereto.

The same effects as those of the first embodiment can be obtained also in the present embodiment. In the present embodiment, since the carbon dioxide generator 17 is disposed on the outer surface of the lid member 2, the carbon dioxide generator is easily accessible and maintenance of the carbon dioxide generator 17 is easily performed without removing the lid member 2 from the housing 1. For example, it becomes easy to check the state of the carbon dioxide generator 17 or replace the carbon dioxide generator 17. Since the carbon dioxide generating agent 17 is disposed on the outer surface of the cover member 2, the generated carbon dioxide can be directly fed to the periphery of the air blowing device 103, and the carbon dioxide concentration in the periphery of the air blowing device 103 can be increased. Thereby, effective attraction of mosquitoes can be achieved.

(fourth embodiment)

Referring to fig. 5, an air blowing device 104 according to a fourth embodiment of the present invention will be described. In the air blowing device 104, the carbon dioxide generating agent 17 contains a substance that generates carbon dioxide upon receiving a stimulus. Such a carbon dioxide generating agent 17 can be realized by a known technique. In the example shown in fig. 5, the carbon dioxide generating agent 17 includes a photocatalyst, and has a property of generating carbon dioxide by receiving light. As the photocatalyst described here, for example, titanium dioxide can be used. In the air blowing device 104, the carbon dioxide generating agent 17 is disposed inside the first space 20, and the light source 18 is disposed in the vicinity of the carbon dioxide generating agent 17. The light source 18 is disposed so that the light 31 can be irradiated toward the carbon dioxide generating agent 17.

In the present embodiment, since the light 31 can be irradiated from the light source 18 toward the carbon dioxide generator 17, the carbon dioxide generator 17 can generate carbon dioxide by receiving the light 31. With this configuration, the carbon dioxide generating agent 17 can be stimulated as necessary to generate carbon dioxide. When the generation of carbon dioxide is not necessary, unnecessary consumption of the carbon dioxide generator 17 can be avoided by not applying a stimulus to the carbon dioxide generator 17 in advance. When the carbon dioxide generator 17 is a generator having a property of generating carbon dioxide by irradiation with ultraviolet light, the light to be irradiated may be ultraviolet light instead of pure light. Here, as an example of the stimulus, an example in which the stimulus is light is shown, but the stimulus is not limited to light, and other types of stimulus may be used.

Fig. 6 shows an air blower 105 as a modification of the air blower of the present embodiment. In the blower 105, the carbon dioxide generating agent 17 is provided in the cover member 2, and the light source 18 is disposed in the housing 1. This configuration is also possible. The light 31 emitted from the light source 18 is incident on the carbon dioxide generating agent 17 provided on the cover member 2, and carbon dioxide is generated from the carbon dioxide generating agent 17.

(fifth embodiment)

An air blowing device according to a fifth embodiment of the present invention will be described with reference to fig. 7 to 8. The air blowing device of the present embodiment includes: a mosquito attracting mode in which carbon dioxide is generated by applying a stimulus to the carbon dioxide generating agent 17 and carbon dioxide is discharged from the suction port 13 as shown in fig. 7; a mosquito catching mode in which mosquitoes entering the first space 20 are restrained from exiting the first space 20 by the blower fan 5 (refer to fig. 5, 6) sucking air from the suction port 13 as shown in fig. 8.

In the present embodiment, since the air blowing device has both the mosquito attracting mode and the mosquito trapping mode, it is possible to effectively perform continuous operations such as attracting mosquitoes first and then trapping them. In the mosquito suction mode, since the purpose is to discharge carbon dioxide from the suction port 13 as shown in fig. 7, it is preferable that there is no air flow from the inflow port 11 toward the outflow port 12. Therefore, in the mosquito attracting mode, the blower fan 5 is preferably stopped first. In the mosquito trapping mode, air is sucked from the suction port 13 by operating the blower 5, so that the amount of carbon dioxide discharged from the suction port 13 to the outside can be reduced as compared to when the blower fan 5 is stopped. Therefore, in order to suppress unnecessary consumption of the carbon dioxide generating agent 17, it is preferable to stop the application of the stimulus to the carbon dioxide generating agent 17 in advance in the mosquito trapping mode. However, the stimulation of the carbon dioxide generating agent 17 may also be continued during the mosquito capture mode. In the mosquito trapping mode, even when the carbon dioxide continues to be generated from the carbon dioxide generating agent 17 while the blower fan 5 is operated, part of the carbon dioxide enters the housing 1 through the inlet port 11 and is discharged through the outlet port 12, so that the carbon dioxide concentration around the blower can be kept high. By keeping the carbon dioxide concentration around the blower high, the attraction of mosquitoes can be promoted.

(embodiment 6)

Referring to fig. 9, an air blowing device 106 according to a sixth embodiment of the present invention will be described. In the air blowing device 106, the carbon dioxide generating agent 17 has a property of generating carbon dioxide by applying moisture. In air blower 106, carbon dioxide generating agent 17 is disposed in first space 20, and water supply unit 19 is disposed in the vicinity of carbon dioxide generating agent 17. The water supply unit 19 is disposed so that the water droplets 32 can drop toward the carbon dioxide generator 17. The water supply section 19 may also include a pipe to carry water. The water supply unit 19 may be provided with a container for storing water in advance. When the blower device 106 has a function of making moisture in the air into water droplets, the water supply unit 19 may be configured to guide the water droplets to the vicinity of the carbon dioxide generating agent 17.

In the present embodiment, since water droplets from the water supply part 19 can be dropped toward the carbon dioxide generator 17, the carbon dioxide generator 17 receives the water droplets 32 to generate carbon dioxide. With this configuration, the carbon dioxide generating agent 17 can be stimulated as necessary to generate carbon dioxide.

As shown in the fourth and sixth embodiments, the stimulus for causing the carbon dioxide generating agent to generate carbon dioxide may be light irradiation or moisture supply.

(seventh embodiment)

With reference to fig. 10 to 13, an air blowing device according to a seventh embodiment of the present invention will be described. Fig. 10 shows a cross-sectional view of the blower. The drawing is a drawing in which the blower is cut in a horizontal cross section, and only the main part is shown. The screen 4 is provided on the back side of the case 1. The lid member 2 is detachably attached so as to be spaced apart from the filter net 4 and cover the filter net 4. The enlarged Z-section of the side of the sieve 4 is shown in fig. 11.

As shown in fig. 11, by providing a wall 41 inside the housing 1, a part of the internal space of the housing 1 is partitioned as a space 40. The casing 1 and the inflow port 11 provided with the strainer 4 have another opening 44. The opening 44 is provided with a flute 43. The flute 43 is configured in such a manner that all air passing through the opening 44 passes through the flute 43. A lid 45 is disposed on the outside of the flute 43 of the opening 44 to be openable and closable. The wall 41 has an opening 42. The air introduced into the space 40 through the opening 44 and the whistle 43 is configured to pass through the opening 42 and exit from the space 40.

In this air blowing device, as shown in fig. 12, in the case where dust 35 accumulates in the screen 4 and it becomes difficult for air to pass through the screen 4, it is set that air enters into the casing 1 through the opening portion 42 and the opening portion 44. This increases the amount of air passing through the opening 44. The flute 43 emits a sound as the air passing through the opening 44 passes through the flute 43. When the user hears the sound of the whistle 43, it is known that the filter net 4 is in a state that should be cleaned. In the case where the user cannot immediately start cleaning the filter net 4 and wants to stop the sound of the whistle 43, the user may close the cover 45 as shown in fig. 13. By closing the cover 45, air becomes unable to pass through the whistle 43, and the whistle 43 becomes unable to sound. Since the screen 4 is not completely clogged at present and a part of air can pass through, the blower can be used even in a state where the cover 45 is closed.

Further, a plurality of the above embodiments may be combined as appropriate. The above-described embodiments disclosed herein are illustrative in all respects, and not restrictive. The scope of the present invention is indicated by the scope of the claims, and includes all modifications within the scope and meaning equivalent to the claims.
