Patent Document 1 discloses a combination of a carbon dioxide gas cylinder, a gas control device, a heater, and a control circuit as an example of a mosquito induction device.

Patent Document 1: Japanese Patent Application Laid-Open No. 2009-250463

Carbon dioxide gas cylinders, gas control devices, etc. are relatively large in volume, so they should not be installed in air purifiers. When the carbon dioxide gas stored in the carbon dioxide bottle disappears, it needs to be replaced, which is inconvenient.

Therefore, an object of the present invention is to provide a blower capable of attracting mosquitoes while having a compact structure.

In order to achieve the above object, the air blowing device of the present invention includes a housing having an air inlet and an outlet, a blower fan provided in the housing, and a housing cover member that is detachably attached to the inlet space and at the inlet port The outside defines the first space and has a suction port for air to the first space; and a cover member, which is arranged in the first space or outside the cover member, and also has a carbon dioxide generator.

According to the present invention, carbon dioxide can be generated by the carbon dioxide generating agent disposed outside the first space or the cover member. Since mosquitoes are attracted by carbon dioxide, a blower having a compact structure capable of attracting mosquitoes can be realized.

(Embodiment 1) Referring to Figs. 1 and 2, a blower 101 in a first embodiment based on the present invention will be described. An external perspective view of the air blowing device 101 is shown in FIG. 1. A cross-sectional view of the air blowing device 101 is shown in FIG. 2. The air blowing device 101 includes a casing 1 having an inflow inlet 11 and an air outlet 12, and an air supply fan 5 provided in the casing 1 is detachably connected to the casing 1 to cover the inflow inlet 11 in the first space 20 of the inflow inlet 11, The outside of the cover member 2 having the air inlet 13 to the first space 20 is defined, and the cover member 2 and the carbon dioxide generator 17 provided inside or outside the first space 20 are defined. In the present embodiment, the carbon dioxide generator 17 is provided in the first space 20.

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

In the present embodiment, the air blowing device 101 can generate carbon dioxide by including a carbon dioxide generator 17 provided outside the first space 20 or the cover member 2. Since the mosquito is attracted by carbon dioxide, the air blowing device 101 of this embodiment can attract the mosquito and has a compact structure. The air blowing device 101 in the present embodiment is not limited to mosquitoes, and insects that can attract carbon dioxide substances. Examples of insects attracted by carbon dioxide include flies.

As shown in FIG. 2, the carbon dioxide generator 17 is preferably disposed on the upper portion of the first space 20 of the cover member 2. Carbon dioxide is heavier than air and therefore tends to flow downwards. As described in this embodiment, if the carbon dioxide generator 17 is provided on the top of the first space 20, the carbon dioxide generated from the carbon dioxide generator 17 is easy to propagate throughout the first space 20.

(Embodiment 2) Referring to Fig. 3, a blower 102 according to a second embodiment of the present invention will be described. In the air blowing device 102, the carbon dioxide generator 17 is supported on the inner surface of the cover member 2. The other configurations are the same as those described in the first embodiment.

Also in this embodiment, effects similar to those of Embodiment 1 can be obtained. In this embodiment, since the carbon dioxide generator 17 is composed of the cover member 2, when the cover member 2 is removed from the housing 1, the carbon dioxide is supported together with the cover member 2 and can be taken out. Therefore, in this embodiment, maintenance of the carbon dioxide generator 17 is easily performed. Since the carbon dioxide generator is disposed on the inner surface of the cover member 2 when the blower device 102 is viewed from the outside, the blower device 102 can be cleaned without the visible carbon dioxide generator 17.

(Embodiment 3) Referring to Fig. 4, a blower 103 according to a third embodiment of the present invention will be described. In the blower 103, the carbon dioxide generator 17 is supported on 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 generator 17 has a simple rectangular shape, and the purpose is to show the shape of the actual carbon dioxide generator 17 only schematically.

Also in this embodiment, effects similar to those of Embodiment 1 can be obtained. In the present embodiment, since the carbon dioxide generator 17 is provided on the outer surface of the cover member 2, maintenance of the carbon dioxide generator 17 by removing the carbon dioxide generator 17 from the cover member 2 is easy. For example, it is easy to confirm the state of the carbon dioxide generator 17 or to exchange the carbon dioxide generator 17. Since the carbon dioxide generator 17 is provided on the outer surface of the cover member 2, it can be directly transferred to the carbon dioxide generated around the air blowing device 103 to increase the carbon dioxide concentration in the surrounding air blowing device 103. By doing so, you can effectively attract mosquitoes.

(Embodiment 4) Referring to Fig. 5, a blower 104 in a fourth embodiment according to the present invention will be described. In the air blowing device 104, the carbon dioxide generator 17 contains a substance which generates carbon dioxide when stimulated. 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 mentioned here, for example, titanium dioxide can be used. In the air blowing device 104, the carbon dioxide generator 17 is arranged in the first space 20, and the light source 18 is disposed near the carbon dioxide generator 17. The light source 18 is configured to be able to irradiate the light 31 toward the carbon dioxide generator 17.

In the present embodiment, since the light 31 from the light source 18 can be radiated toward the carbon dioxide generator 17, the carbon dioxide generator 17 receives the carbon dioxide generated by the light 31. By adopting this configuration, carbon dioxide can be generated by stimulating the carbon dioxide generator 17 as necessary. When there is no need to generate carbon dioxide, unnecessary consumption of the carbon dioxide generator 17 can be avoided by not stimulating the carbon dioxide generator 17 in advance. When the carbon dioxide generator 17 has a property of generating carbon dioxide by irradiation with ultraviolet light, the irradiated light may be not only light but also ultraviolet light. Here, as an example of the stimulus, an example in which the stimulus is light is shown, but it is not limited to light, and other types of stimulus may be used.

FIG. 6 shows an air blowing device 105 as a modification of the air blowing device of the present embodiment. In the air blowing device 105, the carbon dioxide generator 17 is installed in the cover member 2, and the light source 18 is arranged in the casing 1. This configuration can be adopted. The light 31 emitted from the light source 18 enters the carbon dioxide generator 17 provided on the cover member 2, and the carbon dioxide generated from the carbon dioxide generator 17.

(Embodiment 5) Referring to Figs. 7-8, a blower according to a fifth embodiment of the present invention will be described. Air-supplying device In this embodiment, by applying a stimulus to the carbon dioxide generator 17 to generate carbon dioxide, and in a mosquito attracting mode for discharging carbon dioxide from the suction port 13 as shown in the figure, the air-supplying fan 5 (as shown in FIG. It is shown that air is sucked in from the suction port 13 as shown in FIG. 8 by reference to FIG. 6), and mosquitoes are inhibited from entering and exiting from the first space 20.

In this embodiment, the air-supplying device is so provided with two mosquito attracting modes and a mosquito collecting mode, which can effectively perform a series of operations, which collect and attract mosquitoes in advance. In the mosquito attracting mode, since the purpose is to discharge carbon dioxide from the suction port 13, as shown in FIG. 7, it is preferable that the flow of air not guided from the inflow port 11 to the blowout port 12. Therefore, in the mosquito suction mode, the air-supply fan 5 is preferably stopped. In the mosquito trapping mode, when the blower fan 5 is operated, the blower fan 5 stops sucking air from the suction port 13 and the amount of carbon dioxide leaving the suction port 13 to the outside is reduced. Therefore, in order to suppress unnecessary consumption of the carbon dioxide generator 17, that is, the carbon dioxide generator 17 in the mosquito-capturing mode stimulation is preferably kept stopped. However, the carbon dioxide generator 17 may also be stimulated during the mosquito collection mode. Even if the blower fan 5 continues to generate carbon dioxide from the carbon dioxide generator 17 during operation as a capture mode mosquito, and enters a part of the carbon dioxide inflow port 11 in the housing 1 and is discharged from the blowout port 12, the carbon dioxide concentration around the blower can be Keep it high. By keeping the concentration of carbon dioxide around the blast device high, the attraction of mosquitoes can be promoted.

(Embodiment 6) An air blower 106 according to Embodiment 6 of the present invention will be described with reference to Fig. 9. In the air blowing device 106, the carbon dioxide generator 17 has a property of generating carbon dioxide by applying moisture. The air supply device 106 and the carbon dioxide generator 17 are arranged in a first space 20. A water supply unit 19 is provided near the carbon dioxide generator 17. The water supply unit 19 is arrange | positioned so that the water droplet 32 may drip to the carbon dioxide generator 17 side. The water supply unit 19 may include a pipe for carrying water. The water supply unit 19 may be provided with a container that stores water in advance. When the air blowing device 106 is provided with a function in the air to create water droplets from the moisture, the supply unit 19 may generate the water droplets in a structure near the carbon dioxide generator 17.

In this embodiment, since the water droplets of the water supply unit can descend toward the carbon dioxide generator 17, the carbon dioxide generator 17 generates carbon dioxide by receiving the water droplets 32. By adopting this configuration, carbon dioxide can be generated by stimulating the carbon dioxide generator 17 as necessary.

As shown in Examples 4 and 6, the stimulus for generating carbon dioxide in the carbon dioxide generator may be light irradiation or moisture supply.

(Embodiment 7) With reference to Figs. 10 to 13, a blower device according to a seventh embodiment of the present invention will be described. FIG. 10 shows a cross-sectional view of the air supply device. In this figure, the blower is cut in a horizontal section, and only the main part is shown. The screen 4 is mounted on the rear side of the casing 1. The cover member 2 is detachably attached and detached so as to cover the screen 4 in a state separated from the screen 4. FIG. 11 shows an enlarged Z portion of the side of the screen 4.

As shown in FIG. 11, a wall portion 41 is provided inside the casing 1, and a part of the internal space of the casing 1 is divided into a space 40. The housing 1 has an opening 44 separate from the inflow port 11 to which the screen 4 is installed. The groove 43 is provided in the opening 44. The groove 43 is arranged such that all air passing through the opening 44 passes through the groove 43. A cover 45 that can be opened and closed is provided outside the groove 43 of the opening 44. The wall 41 has an opening 42. The air entering the space 40 through the opening 44 and the groove 43 is configured to be able to leave the space 40 through the opening 42.

In the air blowing device, as shown in FIG. 12, when the dust 35 in the air accumulated in the filter 4 has passed through the opening 42 and the opening 4 through the filter 4, the air becomes ready to enter the housing 1. This increases the amount of air passing through the opening 44. Since the air passing through the opening 44 passes through the groove 43, the groove 43 emits a sound. When the user hears the sound of the groove 43, the user knows that the screen 4 is in a state to be cleaned. If the user cannot immediately start cleaning the filter 4 to stop the sound of the groove 43, as shown in FIG. 13, the user can close the cover 45. By closing the cover 45, air does not pass through the groove 43 and the sound of the groove 43 is not emitted. Since the strainer 4 has not been completely blocked and some air can pass through, the blower can be used even after the cover 45 is closed.

Note that a plurality of the above-described embodiments may be appropriately combined and adopted. It should be noted that the above-mentioned embodiments disclosed this time are illustrative and not restrictive in all respects.
