Description

Chemical volatilization tool and chemical volatilization device

[0001] The present invention relates to a drug volatilization device that includes a drug volatilization body that volatilizes a volatile drug and a volatilization container that contains the drug volatilization body, and to a drug volatilization device that includes the drug volatilization device.

[0002] For example, chemical volatilizers are used to volatilize volatile chemicals such as air fresheners, deodorants, repellents, and insecticides (see, for example, Patent Documents 1 to 3).

[0003] Patent documents 1 to 3 disclose chemical volatilization devices that include a chemical volatilizer that volatilizes a volatile chemical and a volatilization container that contains the chemical volatilizer. In these chemical volatilization devices, the volatilization container has a ventilation surface portion formed with an opening that connects the outside and the inside of the volatilization container.

[0005] The pesticide volatilization devices in Patent Documents 1 to 3 do not have a structure that actively guides air flowing toward the volatilization container due to the wind current toward the volatilization surface, so there is room for improvement in terms of taking in more air inside the container.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a drug volatilization device and a drug volatilization apparatus that can take in more air into the volatilization container.

[0007] The characteristic configuration of the drug volatilization device of the present invention for solving the above problems is that it is a drug volatilization device comprising a drug volatilization body that volatilizes a volatile drug and a volatilization container that contains the drug volatilization body, wherein the volatilization container has a ventilation surface portion in which a communication opening that connects the outside and inside of the volatilization container is formed, and a protrusion portion that protrudes outward at an incline from the ventilation surface portion.

[0008] With this chemical volatilization device, of the air flowing toward the volatilization container, the air flowing toward the ventilation surface portion on which the communication opening is formed is directly taken into the interior of the volatilization container through the communication opening. On the other hand, the air flowing toward the protruding portion that protrudes outward from the ventilation surface portion is guided along the protruding portion to the ventilation surface portion by the guiding function of the protruding portion and is taken into the interior of the volatilization container through the communication opening. In this way, in addition to the air flowing toward the ventilation surface portion, the air flowing toward the protruding portion is taken into the interior of the volatilization container through the communication opening formed in the ventilation surface portion, so more air can be taken into the interior of the volatilization container.

[0009] In the drug volatilization device of the present invention, it is preferable that the volatilization container is a columnar body having opposing surfaces, and the ventilation surface portions are each arranged on the opposing surfaces.

[0010] With this chemical volatilizer, air flowing toward one of the ventilation surfaces arranged on opposite sides of the volatilizer and the protruding portion inclined outward relative to the ventilation surface is drawn into the volatilizer as described above. The chemical-containing air drawn into the volatilizer is released to the outside through a communication opening in the other ventilation surface arranged on the opposite sides of the volatilizer. The released chemical-containing air flows along the protruding portion, guided by the protruding portion inclined outward relative to the other ventilation surface, toward a wider external area. As a result, more chemical-containing air can be diffused to a wider external area of ​​the volatilizer, allowing the chemical to be more efficiently volatilized.

[0011] In the chemical volatilizer of the present invention, it is preferable that the angle of inclination of the protruding portion relative to the ventilation surface portion is set to 110 to 165 degrees.

[0012] If the inclination angle of the protruding portion relative to the ventilation surface portion is brought closer to 180 degrees, the air intake area for the air flowing toward the volatilization container can be increased, but the guiding function of the protruding portion is not fully exerted, and the air flowing along the protruding portion toward the ventilation surface portion decreases, resulting in a decrease in the amount of air taken into the storage portion. On the other hand, if the inclination angle of the protruding portion relative to the ventilation surface portion is brought closer to 90 degrees, the air intake area decreases, resulting in a decrease in the amount of air taken into the storage portion. Therefore, with this chemical volatilization device, the inclination angle of the protruding portion relative to the ventilation surface portion is set to 110 to 165 degrees. This allows the guiding function of the protruding portion to be fully exerted while ensuring a sufficient air intake area, ensuring that more air is reliably taken into the interior of the volatilization container.

[0013] In the drug volatilizer of the present invention, the protruding portion preferably has a concavely curved inclined surface recessed inward.

[0014] With this configuration of chemical volatilizer, air flowing toward the protruding portion flows more smoothly along the inwardly recessed, curved inclined surface toward the ventilation surface portion, allowing air to be efficiently taken into the inside of the volatilization container.

[0015] In the chemical volatilization device of the present invention, it is preferable that the protruding portion is arranged on at least the lower base when the volatilization container is placed.

[0016] According to the chemical volatilizer of this configuration, a protruding portion is provided on at least the lower base when the volatilization container is placed, so that the stability of the placed state can be increased by the protruding portion.

[0017] In the chemical volatilization device according to the present invention, it is preferable that the communication opening is formed so as to extend in the vertical direction when the volatilization container is placed.

[0018] With this configuration of chemical volatilization device, a communicating opening is formed so as to extend vertically when the volatilization container is placed on the surface, thereby ensuring that air flowing from the protruding portion to the ventilation surface portion flows along the communicating opening, allowing air to be efficiently taken into the interior of the volatilization container.

[0019] In the chemical volatilizer of the present invention, it is preferable that the protruding portion is provided with a rectifying fin that rectifies the air flow so that it is directed toward the communication opening.

[0020] With this configuration of chemical volatilizer, the rectifying fins rectify the air flow so that it is directed toward the communicating opening, so that air flowing toward the ventilation surface can be reliably guided to the communicating opening.

[0021] Next, the characteristic configuration of the chemical volatilization device according to the present invention for solving the above problem is that it is configured by arranging multiple chemical volatilization devices described above in series.

[0022] According to the chemical volatilization device of this configuration, the volatilization performance can be easily adjusted by adjusting the number of chemical volatilization devices that are connected together.

[0023] In the drug volatilization device of the present invention, it is preferable that the multiple drug volatilization tools are rotatable relative to each other via a connecting means.

[0024] According to the drug volatilization device of this configuration, the drug volatilization devices have connecting means, and adjacent drug volatilization devices can rotate relative to each other via the connecting means.The installation area can be increased by connecting multiple drug volatilization devices, and adjacent drug volatilization devices can be arranged so that they cross each other, which increases the stability of the placed state.Even if the direction of air flow changes, the probability that air will be drawn into the volatilization container of one of the multiple drug volatilization devices can be increased, allowing the drug to be volatilized stably and efficiently.

Fig. 3 is an explanatory diagram of the air intake action, etc., of the chemical volatilizer in an upright position.

Fig. 5 is a plan view of a chemical volatilizer according to one embodiment of the present invention. Fig. 6 is an explanatory diagram of a chemical volatilizer according to another embodiment 1. Fig. 7 is an explanatory diagram of a chemical volatilizer according to another embodiment 2.

[0026] The present invention will be described below with reference to the drawings. However, the present invention is not intended to be limited to the embodiments described below or the configurations shown in the drawings.

[0027] <Overall Configuration> Figure 1 is an external view of a drug volatilizer 1 according to one embodiment of the present invention. Figure 1(a) is a perspective view from the front side, and Figure 1(b) is a perspective view from the back side. Figure 1(c) is a view as viewed from the arrow A in Figure 1(a). As shown in Figure 1(a), the drug volatilizer 1 of this embodiment includes a drug volatilizer 2 that volatilizes a volatile drug and a volatilization container 3 that contains the drug volatilizer 2. The volatilization container 3 can be manufactured, for example, by a known resin molding method such as injection molding using a resin as a material, but is not limited thereto. Although detailed illustrations are omitted, the volatilization container 3 has, for example, an insertion port (not shown) through which the drug volatilizer 2 can be inserted and removed from the storage section 3a, and an opening / closing structure (not shown) that opens and closes the insertion port by, for example, attaching, detaching, or sliding a lid (not shown) that covers the insertion port.

[0028] <Volatile Agents> Volatile agents include insecticides, repellents, antifungal agents, antibacterial agents, fragrances, deodorizers, synergists, etc., which can be used alone or in combination, but are not particularly limited to these. For example, when used for the purpose of exterminating or repelling flying pests such as mosquitoes, midges, and moth flies, it is preferable to use a pyrethroid compound as the volatile agent, and in particular, pyrethroid compounds that are volatile at room temperature, such as metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatility and control effect against flying pests, are suitable. Note that volatile agents can be used in combination with known, hardly volatile agents, etc.

[0029] <Drug volatilizer> The drug volatilizer 2 can be, for example, one configured to hold a volatile drug in a volatilizable manner by impregnation or kneading. Examples of materials for the drug volatilizer 2 include paper, pulp, natural fibers, synthetic fibers, resin bodies, resin sheets, inorganic and organic porous bodies, gel-like bodies, and the like. While impregnating a resin sheet with the drug is a simple method for holding the drug in the drug volatilizer 2, it is preferable to use a resin kneaded with a volatile drug because it is easier to control the sustained release of the volatile drug during use, the amount of drug volatilization is stable, and when used outdoors, it prevents the drug from being washed away by moisture such as rain. However, this is not particularly limited. Examples of resins for the resin body and resin sheet include polyethylene, polypropylene, polyvinyl alcohol, polyvinyl acetate, polybutadiene, polyisoprene, ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate copolymer, styrene-butadiene copolymer, and the like. The shape of the drug volatilizer 2 is not particularly limited to sheet-like, granular, three-dimensional, etc., but from the perspective of improving the volatilization efficiency of the volatile drug, for example, a honeycomb structure, a perforated structure, a flat or three-dimensional mesh structure, etc. can be adopted.

[0030] <Volatilization container> As shown in Figures 1(a) and (b), the volatilization container 3 is a columnar body having two sets of opposing surfaces (a front surface 11 and a back surface 12 (first set) described below, and a right side surface 13 and a left side surface 14 (second set) described below), and is equipped with a thin rectangular parallelepiped container body 4 that is long in the vertical direction and short in depth, and a pair of end structures 5A, 5B connected to one end side (upper end side) and the other end side (lower end side) of the container body 4, respectively. Note that in this example, the volatilization container 3 (container body 4) is an example of a columnar body having a rectangular cross section, but is not limited to this and may be, for example, a columnar body having a rounded rectangular cross section.

[0031] <Container body> The container body 4 has a front portion 11 (see FIG. 1(a)), a back portion 12 (see FIG. 1(b)), a right side portion 13 (see FIG. 1(a)), and a left side portion 14 (see FIG. 1(c)). The front portion 11 and the back portion 12 are both formed in a rectangular shape (oblong shape) that is long in the vertical direction. The front portion 11 and the back portion 12 are arranged opposite each other with a predetermined interval in the horizontal direction. As shown in FIGS. 1(a) and 1(c), the right side portion 13 and the left side portion 14 are both formed in a rectangular shape (strip shape) that is long in the vertical direction. The right side portion 13 and the left side portion 14 are arranged opposite each other with a predetermined interval in between at both side edges of the front portion 11 and the back portion 12 so as to be perpendicular to the front portion 11 and the back portion 12. The container body 4 is configured such that the side edges of the front portion 11, the back portion 12, and the right side portion 13 and the left side portion 14 are integrally joined together.

[0032] <Ventilation surface portion, communication opening> The front portion 11, the back portion 12, the right side portion 13, and the left side portion 14 each correspond to the "ventilation surface portion" of the present invention. The front portion 11 and the back portion 12 are respectively arranged on opposing sides of the volatilization container 3, and the right side portion 13 and the left side portion 14 are respectively arranged on opposing sides of the volatilization container 3 at right angles to the front portion 11 and the back portion 12. As shown in FIG. 1(a), the front portion 11 has a plurality (eight in this example) of rectangular communication openings 21 that are elongated in the horizontal direction (left-right direction) and are drilled at predetermined intervals in the vertical direction so as to connect the outside and the inside of the volatilization container 3. As shown in FIG. 1(b), the back portion 12 has a plurality (eight in this example) of communication openings 22 formed in the same shape as the communication openings 21 so as to connect the outside and the inside of the volatilization container 3. 1(a), the right side surface portion 13 is provided with a plurality of (eight in this example) rectangular communication openings 23 that are slightly elongated in the depth direction (front-to-back direction) and are spaced apart at predetermined intervals in the vertical direction so as to communicate between the outside and the inside of the volatilization container 3. As shown in FIG. 1(c), the left side surface portion 14 is provided with a plurality of (eight in this example) communication openings 24 that are shaped similarly to the communication openings 23 and communicate between the outside and the inside of the volatilization container 3.

[0033] <Protrusion> As shown in Figure 1 (a), the end structures 5A and 5B respectively constitute the upper and lower parts of the volatilization container 3 when the volatilization container 3 is placed on the mounting surface FL. The end structures 5A and 5B function as upper and lower bases, respectively. In particular, the end structure 5B, which functions as the lower base on which the volatilization container 3 is placed, has a protrusion 6 described below, which can increase the stability of the volatilization container 3 when placed. The end structures 5A and 5B have a vertically symmetrical structure and include a protrusion 6 integrally formed with the container body 4 and an end plate 7 integrally formed with the protrusion 6. Note that the end structures 5A and 5B do not necessarily have to be vertically symmetrical and may have an asymmetrical structure. The overhanging portion 6 includes a front overhanging portion 31 (see FIG. 1( a)), a rear overhanging portion 32 (see FIG. 1( b)), a right overhanging portion 33 (see FIG. 1( a)), and a left overhanging portion 34 (see FIG. 1( c)). As shown in FIG. 1( a), the front overhanging portion 31 is formed to overhang at an outward incline relative to the front portion 11. As shown in FIG. 1( b), the rear overhanging portion 32 is formed to overhang at an outward incline relative to the rear portion 12. As shown in FIGS. 1( a) and 1( b), the right overhanging portion 33 is formed to overhang at an outward incline relative to the right side surface portion 13. As shown in FIG. 1( c), the left overhanging portion 34 is formed to overhang at an outward incline relative to the left side surface portion 14.

[0034] FIG. 2 is an explanatory diagram of the overhang portion 6. FIG. 2( a) is a diagram illustrating the front overhang portion 31 when the surface of the overhang portion 6 is flat. FIG. 2( b) is a diagram illustrating the left overhang portion 34 when the surface of the overhang portion 6 is flat. FIG. 2( c) is a diagram illustrating the front overhang portion 31 when the surface of the overhang portion 6 is concavely curved. FIG. 2( d) is a diagram illustrating the left overhang portion 34 when the surface of the overhang portion 6 is concavely curved. Note that the front overhang portion 31 and the rear overhang portion 32 have similar structures, and therefore the structure of the rear overhang portion 32 will be described by explaining the structure of the front overhang portion 31 using FIGS. 2( a) and 2(c). Also, the right overhang portion 33 and the left overhang portion 34 have similar structures, and therefore the structure of the right overhang portion 33 will be described by explaining the structure of the left overhang portion 34 using FIGS. 2(b) and 2(d).

[0035] As shown in Fig. 2(a), the front-side overhanging portion 31 has a planar inclined surface 41 formed in a plane along the overhanging direction (the direction of the arrow D in Fig. 2(a)) of the front-side overhanging portion 31. Similarly, as shown in Fig. 2(b), the left-side overhanging portion 34 has a planar inclined surface 42 formed in a plane along the overhanging direction (the direction of the arrow D in Fig. 2(b)).

[0036] In FIG. 2A, the inclination angle of the front projection 31 with respect to the front surface 11 (the angle between the outer surface of the front surface 11 and the planar inclined surface 41 of the front projection 31) is defined as θ １ 2B, the inclination angle of the left side protrusion 34 with respect to the left side surface 14 (the angle formed between the outer surface of the left side surface 14 and the flat inclined surface 42 of the left side protrusion 34) is θ ２ Let's say.

[0037] The tilt angle θ in FIGS. １ and θ ２ If the inclination angle θ is brought closer to 180 degrees, the air intake area for the air flowing toward the volatilization container 3 can be increased, but the guiding function of the front side protrusion 31 and the left side protrusion 34 is not fully exerted, and the amount of air flowing along the front side protrusion 31 and the left side protrusion 34 to the front part 11 and the left side part 14 decreases, resulting in a decrease in the amount of air taken into the storage part 3a (see FIG. 1(a)). １ and θ ２ If the angle is brought closer to 90 degrees, the area in which air can be taken in will decrease, and as a result, the amount of air taken into the storage section 3a will decrease.

[0038] Therefore, in this embodiment, the inclination angle θ １ and θ ２ is preferably set to 110 to 165 degrees, and more preferably set to 120 to 150 degrees. This allows the guide functions of the front projection 31 and the left projection 34 to be fully exerted while ensuring a sufficient air intake area, and more air can be reliably taken into the interior of the volatilization container 3 (the storage section 3a (see FIG. 1(a))). In this example, the inclination angle θ １ is set to about 135 degrees, and the inclination angle θ ２is set to about 140 degrees.

[0039] The configuration of the front overhanging portion 31 is not limited to the configuration having a flat inclined surface 41 as shown in FIG. 2( a). For example, as shown in FIG. 2( c), the front overhanging portion 31 may have an inwardly recessed concavely curved inclined surface 43, more specifically, a concavely curved inclined surface 43 recessed in a concavely curved shape in a direction intersecting (or perpendicular to) the protruding direction of the front overhanging portion 31 (the direction of the arrow D in FIG. 2( c)). Similarly, the configuration of the left overhanging portion 34 is not limited to the configuration having a flat inclined surface 42 as shown in FIG. 2( b). For example, as shown in FIG. 2( d), the left overhanging portion 34 may have an inwardly recessed concavely curved inclined surface 44, more specifically, a concavely curved inclined surface 44 recessed in a concavely curved shape in a direction intersecting (or perpendicular to) the protruding direction of the left overhanging portion 34 (the direction of the arrow D in FIG. 2( d)). By configuring the container with such concavely curved inclined surfaces 43, 44, air flowing toward the protrusions 31, 34 flows more smoothly along the concavely curved inclined surfaces 43, 44 to the ventilation surface portions (front portion 11, left side portion 14), thereby enabling air to be efficiently taken into the interior of the volatilization container 3 (storage portion 3a (see Figure 1 (a))).

[0040] In FIG. 2C, the inclination angle of the front projection 31 relative to the front surface 11 is considered to be the angle formed by a straight line La tangent to two edges spaced apart in the projection direction of the front projection 31 on the concavely curved inclined surface 43 (the direction of the arrow D in FIG. 2C) and the outer surface of the front surface 11, and this angle is defined as θ ３ 2(d), the inclination angle of the left side protrusion 34 with respect to the left side surface 14 is regarded as the angle formed by a straight line Lb, which is tangent to two edges of the concavely curved inclined surface 44 that are spaced apart in the protrusion direction of the left side protrusion 34 (the direction of the arrow D in FIG. 2(d)), and the outer surface of the left side surface 14, and this angle is defined as θ ４ Let's say.

[0041] Incline angle θ ３ and θ ４ Regarding the inclination angle θ １ and θ ２Similarly, in consideration of the balance between the air intake area and the guiding function for the inclination angle described above, the inclination angle θ ３ and θ ４ is preferably set to 110 to 165 degrees, and more preferably set to 120 to 150 degrees. This allows the guide functions of the front projection 31 and the left projection 34 to be fully exerted while ensuring a sufficient air intake area, and more air can be reliably taken into the interior of the volatilization container 3 (the storage section 3a (see FIG. 1(a))). In this example, the inclination angle θ ３ is set to about 135 degrees, and the inclination angle θ ４ is set to about 140 degrees.

[0042] 3A and 3B are explanatory diagrams of the air intake operation and the like by the chemical volatilizer 1 in an upright position. Fig. 3A is an explanatory diagram of the air intake operation and the chemical volatilization operation by the chemical volatilizer 1 when air flows toward the left side of the volatilization container 3. Fig. 3B is an explanatory diagram of the air intake operation and the chemical volatilization operation by the chemical volatilizer 1 when air flows toward the front of the volatilization container 3.

[0043] As shown in Figure 3(b), when air flows toward the front of the volatilization container 3 due to the wind current, the air flowing toward the front of the volatilization container 3, of the air flowing toward the front of the volatilization container 3, the air flowing toward the front portion 11 is directly taken into the interior of the volatilization container 3 through the communicating opening 21 (see Figure 1(a)). On the other hand, the air flowing toward the pair of front side overhangs 31 that extend outwardly at an angle relative to the front portion 11 flows along the pair of front side overhangs 31 to the front portion 11 due to the guiding function of the pair of front side overhangs 31, and is taken into the interior of the volatilization container 3 through the communicating opening 21 (see Figure 1(a)). In this way, in addition to the air flowing toward the front portion 11, the air flowing toward the pair of front side overhangs 31 is taken into the interior of the volatilization container 3 through the communicating opening 21 (see Figure 1(a)) formed in the front portion 11, so that more air can be taken into the interior of the volatilization container 3.

[0044] The air containing the drug that has been taken into the volatilization container 3 as described above is released to the outside through the communication opening 22 (see FIG. 1(b)) in the back portion 12 that is arranged opposite the front portion 11. At this time, the released drug-containing air flows toward a wider external area along the pair of back-side protrusions 32 due to the guiding function of the pair of back-side protrusions 32 that protrude outward at an incline relative to the back portion 12. As a result, more air containing the drug can be diffused toward a wider external area of ​​the volatilization container 3, allowing the drug to be more efficiently volatilized.

[0045] In addition, when air flows toward the back of the volatilization container 3, the air intake side and the drug volatilization side are simply reversed from those illustrated in Figure 3(b), and the air intake operation and drug volatilization operation are basically the same as those illustrated in Figure 3(b).Therefore, an explanation of the air intake operation and drug volatilization operation when air flows toward the back of the volatilization container 3 will be omitted.

[0046] Next, as shown in FIG. 3( a), when air flows toward the left side of the volatilization container 3 due to the wind flow, the air flowing toward the left side of the volatilization container 3, of the air flowing toward the left side of the volatilization container 3, is directly taken into the interior of the volatilization container 3 through the communicating opening 24 (see FIG. 1( c)). On the other hand, the air flowing toward the pair of left side protrusions 34 that protrude outward at an angle from the left side of ...

[0047] The air containing the drug that has been taken into the volatilization container 3 as described above is released to the outside through the communication opening 23 (see FIG. 1(a)) in the right side surface 13, which is disposed opposite the left side surface 14. At this time, the released drug-containing air flows toward a wider external area along the pair of right-side protrusions 33 due to the guiding function of the pair of right-side protrusions 33, which protrude outward at an incline relative to the right side surface 13. As a result, more air containing the drug can be diffused toward a wider external area of ​​the volatilization container 3, allowing the drug to be more efficiently volatilized.

[0048] In addition, when air flows toward the right side of the volatilization container 3, the air intake side and the drug volatilization side are simply reversed from those illustrated in Figure 3(a), and the air intake operation and drug volatilization operation are basically the same as those illustrated in Figure 3(a), so we will omit the explanation of the air intake operation and drug volatilization operation when air flows toward the right side of the volatilization container 3.

[0049] 4 is an explanatory diagram of the air intake operation by the chemical volatilizer 1 in a prone position. When the chemical volatilizer 1 is tilted (prone position) from the upright position shown in FIG. 3(b) in which the chemical volatilizer 1 is upright in the vertical direction relative to the mounting surface FL, for example, with the back portion 12 facing the mounting surface FL as shown in FIG. 4, when air flows toward the front of the volatilizer container 3 (the upper surface of the volatilizer container 3 in the prone position shown in FIG. 4) due to the wind flow, the air flowing toward the front of the volatilizer container 3, of the air flowing toward the front portion 11, is directly taken into the volatilizer container 3 through the communication opening 21 (see FIG. 1(a)). On the other hand, air flowing toward a pair of front-side extensions 31 that extend outward at an incline relative to the front portion 11 flows along the pair of front-side extensions 31 toward the front portion 11 due to the guiding function of the pair of front-side extensions 31, and is taken into the interior of the volatilization container 3 through the communicating opening 21 (see Figure 1 (a)).

[0050] As shown in Figure 4, a space S is secured between the rear portion 12 and the mounting surface FL by a pair of end structures 5A, 5B including a pair of rear-side overhanging portions 32 that extend outward at an inclination relative to the rear portion 12. Therefore, the air containing the chemical agent that has been taken into the volatilization container 3 as described above is released to the outside through the space S from the communication opening 22 (see Figure 1 (b)) provided in the rear portion 12. In this way, even when the chemical agent volatilization device 1 is in a fallen position, the air containing the chemical agent can be diffused to the area outside the volatilization container 3.

[0051] 5 is a plan view of a drug volatilization device 50 according to one embodiment of the present invention. Fig. 5(a) is a diagram showing a state in which a plurality of drug volatilization devices 1 are connected in series. Fig. 5(b) is a diagram showing a state in which a plurality of drug volatilization devices 1 are connected in a folding screen (zigzag). As shown in Figs. 5(a) and (b), the drug volatilization device 50 is configured by connecting a plurality of (three in this example) drug volatilization devices 1.

[0052] In the chemical volatilization device 50 illustrated in Figures 5(a) and (b), the connecting means 60 connecting adjacent chemical volatilization devices 1 includes a pair of engaging protrusions 61 and a pair of engaging recesses 62. The pair of engaging protrusions 61 are formed at one end of the end structure 5A in the longitudinal direction (the direction in which the right side surface portion 13 and the left side surface portion 14 are arranged opposite each other) so as to be located on both sides of the end structure 5A in the lateral direction (the direction in which the front surface portion 11 and the back surface portion 12 are arranged opposite each other). The pair of engaging recesses 62 are formed at the other end of the end structure 5A in the longitudinal direction so as to be located on both sides of the end structure 5A in the lateral direction. The engaging recesses 62 are formed in the shape of a C-ring with a portion missing in the circumferential direction. The engaging protrusions 61 are formed in a disk shape (cylindrical shape) that can elastically engage with the engaging recesses 62.

[0053] As shown in Figure 5(a), when a pair of engaging recesses 62 of the drug volatilizer 1 on one side (relatively upper side in Figure 5(a)) of adjacent drug volatilizers 1 are engaged with a pair of engaging protrusions 61 of the drug volatilizer 1 on the other side (relatively lower side in Figure 5(a)), the drug volatilizer 1 on one side and the drug volatilizer 1 on the other side are connected so that they cannot rotate relative to each other, and multiple drug volatilizers 1 are connected in series.

[0054] As shown in Figure 5(b), when adjacent drug volatilizers 1 are fitted with an engaging recess 62 on one side of the drug volatilizer 1 on one side (relatively the upper side in Figure 5(b)) and an engaging protrusion 61 on one side of the drug volatilizer 1 on the other side (relatively the lower side in Figure 5(b)), and the other engaging recess 62 and the other engaging protrusion 61 are disengaged, the drug volatilizer 1 on one side and the drug volatilizer 1 on the other side are connected so that they can rotate relative to each other, and by rotating them around the engagement part between the engaging protrusion 61 and the engaging recess 62 and tilting the drug volatilizer 1 on the other side relative to the drug volatilizer 1 on one side, multiple drug volatilizers 1 are arranged in a folding screen (zigzag) shape.

[0055] In the drug volatilization device 50 shown in Figures 5(a) and (b), the volatilization performance can be easily adjusted by adjusting the number of consecutively arranged drug volatilization devices 1. Also, as shown in Figure 5(b), adjacent drug volatilization devices 1 can be rotated around the engagement portion between the engaging protrusion 61 and the engaging recess 62, so that multiple drug volatilization devices 1 can be arranged so that they intersect with each other. This increases the stability of the mounted state, and also increases the probability that air will be drawn into the volatilization container 3 of one of the multiple drug volatilization devices 1 even if the direction of air flow changes, allowing the drug to be volatilized stably and efficiently.

[0056] The connecting means for connecting adjacent chemical volatilizers 1 to each other is not limited to the connecting means 60. For example, adjacent chemical volatilizers 1 may be connected to each other by a known hinge mechanism, by using links or pins, or by using locking devices with hook-shaped ends.

[0057] The above describes the drug volatilization device and drug volatilization apparatus of the present invention based on one embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration can be changed as appropriate within the scope of the intent thereof.

[0058] (Another embodiment 1) Figure 6 is an explanatory diagram of a drug volatilizer 1A according to another embodiment 1. Figure 6(a) is a front view of the drug volatilizer 1A, and Figure 6(b) is a right side view of the drug volatilizer 1A. As shown in Figure 6(a), the communication openings 21 are provided in a plurality (five in this example) at predetermined intervals in the left-right direction so as to extend in the direction from the protrusion 6 (front protrusion 31) toward the ventilation surface (front portion 11) (in this example, the vertical direction (up-down direction)) when the volatilization container 3 is placed). (The same applies to the communication openings 22.) As shown in FIG. 6(b), the communication openings 23 are drilled at predetermined intervals in the front-to-rear direction so as to extend in a direction from the protrusion 6 (right protrusion 33) toward the ventilation surface portion (right side surface portion 13) (in this example, three) along the vertical direction (vertical direction (up and down)) when the volatilization container 3 is placed). The same applies to the communication openings 24. In this way, the communication openings 21-24 are formed so as to extend along the direction from the protrusion 6 toward the ventilation surface portion (front surface portion 11, back surface portion 12, right side surface portion 13, left side surface portion 14). This ensures that air flowing from the protrusion 6 to the ventilation surface portion (front surface portion 11, back surface portion 12, right side surface portion 13, left side surface portion 14) flows along the communication openings 21-24, allowing air to be efficiently taken into the interior of the volatilization container 3.

[0059] <Straightening Fins> A required number of straightening fins 70 are attached to the overhanging portion 6 (front overhanging portion 31, rear overhanging portion 32, right side overhanging portion 33, left side overhanging portion 34) to straighten the air flow toward the communication openings 21 to 24. The distance between the pair of straightening fins 70 arranged corresponding to each communication opening 21 to 24 gradually decreases as the straightening fins 70 extend from the overhanging portion 6 toward the ventilation surface portion (front portion 11, rear portion 12, right side portion 13, left side portion 14), and the straightening fins are arranged in an eight-shape so that their tips are close to both left and right edges of the lower end of the communication openings 21 to 24. By providing such straightening fins 70, the air flowing toward the ventilation surface (front surface 11, back surface 12, right side surface 13, left side surface 14) can be reliably guided toward the communication openings 21 to 24 by the guidance of the pair of straightening fins 70, and the flow rate of the air can be increased by the constricting effect of the pair of straightening fins 70, which are arranged in an eight-shape so that the tip side is narrowed, thereby allowing the air to be more efficiently taken into the volatilization container 3.

[0060] It goes without saying that the rectifying fins 70 shown in Fig. 6 can also be attached to the protruding portion 6 in an appropriate position in the chemical volatilizer 1 shown in Fig. 3. Also, Fig. 6 shows an example in which the rectifying fins 70 are attached so as to protrude from the surface of the protruding portion 6, but this is not limiting. Although detailed explanation using the drawings will be omitted, for example, a configuration may be used in which multiple recesses having an appropriate depth relative to the surface of the protruding portion 6 are arranged adjacent to each other on the protruding portion 6, and the portions between adjacent recesses (portions protruding relatively to the inner surface of the recesses) function as rectifying fins to cause a rectifying effect.

[0061] (Another embodiment 2) Figure 7 is an explanatory diagram of a medicine volatilizer 1B according to another embodiment 2. Figure 7(a) is a perspective view of the medicine volatilizer 1B as seen from the front side, and Figure 7(b) is a perspective view of the medicine volatilizer 1B as seen from the back side. Figure 7(c) is a view as seen from the arrow B in Figure 7(a). The medicine volatilizer 1B of another embodiment 2 has a basically similar structure to the medicine volatilizer 1 of this embodiment, except for the arrangement of the communication openings 21 to 24.

[0062] In the chemical volatilizer 1B of another embodiment 2, of the multiple communication openings 21 provided in the front portion 11, the uppermost communication opening 21 is arranged adjacent to the front-side protrusion 31 of the upper end structure 5A, and the lowermost communication opening 21 is arranged adjacent to the front-side protrusion 31 of the lower end structure 5B. The same is true for the other multiple communication openings 22 to 24. That is, of the multiple communication openings 22, the uppermost communication opening 22 is arranged adjacent to the back-side protrusion 32 of the upper end structure 5A, and the lowermost communication opening 22 is arranged adjacent to the back-side protrusion 32 of the lower end structure 5B. Of the multiple communication openings 23, the uppermost communication opening 23 is arranged adjacent to the right-side protrusion 33 of the upper end structure 5A, and the lowermost communication opening 23 is arranged adjacent to the right-side protrusion 33 of the lower end structure 5B. Of the multiple communicating openings 24, the top communicating opening 24 is positioned close to the left-side protrusion 34 of the upper end structure 5A, and the bottom communicating opening 24 is positioned close to the left-side protrusion 34 of the lower end structure 5B.

[0063] In the chemical volatilizer 1B configured as described above, the guide function of the protruding portion 6 makes it easier for air flowing toward the protruding portion 6 to flow into the uppermost communicating openings 21-24 and the lowermost communicating openings 21-24, allowing more air to be taken in more efficiently into the volatilization container 3. Also, in the chemical volatilizer 1B, the air that has been taken into the volatilization container 3 and contains the chemical is more likely to flow out from the uppermost communicating openings 21-24 and the lowermost communicating openings 21-24 to the protruding portion 6, allowing more air containing the chemical to be more efficiently volatilized.

[0064] The chemical volatilizer and chemical volatilizer of the present invention can be used not only as a device for volatilizing air fresheners and deodorants, but also particularly effectively in exterminating or repelling flying pests such as mosquitoes, midges, and moth flies.
