With reference to FIG. 5, blower apparatus 104 according to Embodiment 4 of the present invention will be described. In the blower 104, the carbon dioxide generating agent 17 includes a substance that generates carbon dioxide when receiving a stimulus. Such a carbon dioxide generator 17 can be realized by a known technique. In the example shown in FIG. 5, the carbon dioxide generator 17 includes a photocatalyst and has a property of generating carbon dioxide when receiving light. As the photocatalyst here, for example, titanium dioxide can be used. In the blower 104, the carbon dioxide generating agent 17 is arranged inside the first space 20, and the light source 18 is arranged in the vicinity of the carbon dioxide generating agent 17. The light source 18 is arranged so that the light 31 can be emitted toward the carbon dioxide generating agent 17.

  In the present embodiment, light 31 can be emitted from the light source 18 toward the carbon dioxide generating agent 17, and therefore the carbon dioxide generating agent 17 receives the light 31 to generate carbon dioxide. By adopting this configuration, the carbon dioxide generator 17 can be stimulated to generate carbon dioxide as needed. When it is not necessary to generate carbon dioxide, unnecessary consumption of the carbon dioxide generating agent 17 can be avoided by not stimulating the carbon dioxide generating agent 17. When the carbon dioxide generator 17 has a property of generating carbon dioxide by being irradiated with ultraviolet light, the light to be irradiated may be ultraviolet light instead of mere light. Here, an example in which the stimulus is light is shown as an example of the stimulus, but the stimulus is not limited to light and may be another type of stimulus.

  FIG. 6 shows a blower device 105 as a modified example of the blower device according to the present embodiment. In the blower 105, the carbon dioxide generating agent 17 is installed on the cover member 2 and the light source 18 is installed on the housing 1. Such a configuration may be used.

(Embodiment 5)
A blower according to the fifth embodiment of the present invention will be described with reference to FIGS. 7 to 8. The air blower according to the present embodiment generates a carbon dioxide by stimulating the carbon dioxide generator 17 and discharges the carbon dioxide from the suction port 13 as shown in FIG. As shown in FIG. 8 (see FIGS. 5 and 6), a mosquito trapping mode that suppresses mosquitoes that have entered the first space 20 from exiting the first space 20 by sucking air from the suction port 13 is provided. Prepare

  In the present embodiment, since the air blower has both the mosquito attraction mode and the mosquito trapping mode, it is possible to efficiently perform a series of operations of attracting and collecting mosquitoes. Since the purpose of the mosquito attraction mode 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 inlet 11 to the outlet 12. Therefore, it is preferable that the blower fan 5 be stopped in the mosquito attraction mode. In the mosquito trapping mode, air is sucked from the suction port 13 by operating the blower fan 5, so that the amount of carbon dioxide emitted from the suction port 13 is smaller than that 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 stimulating the carbon dioxide generating agent 17 in the mosquito trapping mode. However, the carbon dioxide generator 17 may be continuously stimulated even during the mosquito trapping mode. Even if the carbon dioxide generating agent 17 continues to generate carbon dioxide while the blower fan 5 is operated in the mosquito trapping mode, a part of the carbon dioxide flows from the inflow port 11 into the housing 1. Since the air enters and is discharged from the outlet 12, it is possible to maintain the carbon dioxide concentration around the blower relatively high. By keeping the carbon dioxide concentration around the blower relatively high, the attraction of mosquitoes can be promoted.

The water supply unit 19 is arranged so that the water droplet 32 can be dropped toward the carbon dioxide generating agent 17. The water supply unit 19 may include a pipe for carrying water. The water supply unit 19 may include a container that stores water in advance. When the air blower 106 has a function of producing water droplets from moisture in the air, the water supply unit 19 may have a structure that guides the produced water droplets to the vicinity of the carbon dioxide generating agent 17.

  In the present embodiment, the water droplets 32 can be dropped from the water supply unit 19 toward the carbon dioxide generating agent 17, so that the carbon dioxide generating agent 17 receives the water droplets 32 to generate carbon dioxide. By adopting this configuration, the carbon dioxide generator 17 can be stimulated to generate carbon dioxide as needed.

  As shown in Embodiments 4 and 6, the stimulus for causing the carbon dioxide generator to generate carbon dioxide may be irradiation of light or supply of water.
