Description

  The present invention accommodates a medicine holder holding a medicine or a filter for purifying the airflow, generates an airflow with a fan, diffuses the active ingredient of the medicine into the atmosphere, or cleans the airflow. The present invention relates to an air flow diffusing device.

Conventionally, as an apparatus for diffusing an active ingredient contained in a drug into the atmosphere, as shown in FIG. 11, the drug is stored in the chamber 101 and stored in the chamber 101 while being stored in the chamber 101 and holding the drug. An apparatus 100 is known that applies an air flow using a fan 102 to diffuse an active ingredient contained in the medicine out of the chamber 101 (in the atmosphere) (see, for example, Patent Document 1).
The invention of Patent Document 1 was filed by the present applicant.

In the apparatus 100 described in Patent Document 1, the fan 102 is provided in the middle of the path through which the airflow passes, connecting the intake ports 103 and 103 provided in the chamber 101 and the exhaust ports 104 and 104. At this time, the medicine holder 105 is positioned between the fan 102 and the exhaust ports 104 and 104. In the apparatus 100, the generated airflow is directed substantially in a predetermined direction outside the chamber 101. Therefore, nothing is provided in front of the exhaust ports 104 and 104, so that they are open.
In the following, “the property of releasing the generated airflow in a substantially linear direction toward a predetermined direction” will be described as “directivity”, and “generated airflow is released at a predetermined location with respect to this“ directivity ”. In this case, the property of diffusing radially in the emission direction is described as “diffusibility”. Of course, this “directivity” and “diffusivity” are in a trade-off relationship.

JP-A-11-187799 (FIG. 2)

  By the way, in recent years, development and market sales of this type of apparatus have been activated, and along with this, various demands from consumers have increased. For example, how airflow is generated, decorativeness, and the like can be mentioned.

  In the apparatus described in Patent Document 1, since the discharged airflow is mainly directional, there is room for improvement in regard to the following points in consideration of the consumer demands described above. There seems to be.

  In an apparatus such as that described in Patent Document 1, the air flow generated by the fan 102 is discharged substantially linearly toward the front of the exhaust ports 104 and 104, so that when installed in the vicinity of the human body, the fan 102 The airflow may directly hit the human body. In addition, when used outdoors such as in camping, air currents containing active ingredients may be directly applied to food and drink, leaving room for improvement.

  Furthermore, the exhaust ports 104, 104 are provided as through holes that penetrate the inside and outside of the chamber 101, and nothing is provided in front of them, so that they are open. In some cases, the fan 102 and the medicine holder inside the apparatus are easily visually recognized from the outside by the user, and the decorativeness may be impaired. In addition, the medicine holder can be touched, which is not preferable.

  The present invention has been made in view of the above-mentioned circumstances, and the object thereof is good in appearance and can diffuse the discharge of airflow radially toward the discharge direction. An object of the present invention is to provide an airflow diffusing device capable of simultaneously improving the airflow.

The above-described object of the present invention is achieved by the following configuration.
(1) A drug holding body that holds a drug, a fan that generates an air flow containing an active ingredient contained in the drug by applying an air flow to the drug holding body, and an air flow diffusion that houses the drug holding body and the fan An air flow diffusing device comprising a device main body,
The airflow diffusion device body includes a front case attached to the front side, a rear case attached to the rear side, and a bottom cover that covers the battery accommodated in the bottom,
An exhaust port is provided in front of the front case, an intake port is provided only on a side surface and an upper surface on the back side of the rear case , and the front of the exhaust port is substantially the same as the outer shape of the exhaust port. or shielding plate having a larger outer shape, is provided et the vicinity disposed so as to cover the exhaust port,
The fan is disposed in the middle of the path for the air flow to connect the exhaust port and the intake port;
The airflow diffusing device , wherein the medicine holder is disposed on the rear side of the fan .

According to the configuration of (1) above, the exhaust port is disposed in front of the front case , and the intake ports are disposed only on the side surface and upper surface of the rear case, and the exhaust port is disposed in front of the exhaust port. A shielding plate having an outer shape that is substantially the same or larger than the outer shape is provided so as to cover the exhaust port. As a result, the airflow sucked from the intake port due to the negative pressure generated by the drive of the fan is applied to the medicine holder, and as a result, the airflow containing the medicine is released from the exhaust port. The airflow from the fan is diffused radially toward the discharge direction without flowing almost linearly due to the presence of the shielding plate having an outer shape substantially the same as or larger than the outer shape of the exhaust port. Since the air flow containing the drug can be drifted over a wide range, the diffusibility of the apparatus can be improved. Further, since the shielding plate is provided in front of the exhaust port, the internal structure is not seen from the exhaust port, and the appearance is not impaired. In addition, the presence of the shielding plate can suppress contact with foreign matter (for example, fan wings, electric wires, etc.) disposed in the vicinity of the exhaust port. For example, an infant or the like mistakenly inserts a finger or the like. Since there is no, safety can be improved.
Further , according to the configuration of (1) above , since the drug holding body is arranged on the rear side of the fan, the drug holding body can be arranged on the side that cannot be seen from the front side on the rear side of the airflow diffusion device body. The decorativeness can be improved. In addition, it is necessary to provide a lid such as a cover for attaching / detaching the medicine holder when the medicine holder is periodically replaced, but compared to the case where this lid is provided in front of the shielding plate. The lid can be a simple structure without a complicated structure, and the handleability can be improved .

The introduced airflow passes through the carrier 48 of the medicine holder 15, passes through the wind tunnel portion 28 including the medicine, and hits the shielding plate 17 from the exhaust port 16. As a result, the air flow from the fan 14 does not flow linearly but is diffused radially by the shielding plate 16 toward the discharge direction, and diffuses radially in the front of the exhaust port 16 in a space such as a room. In such a state, an air flow containing the above-mentioned drug is drifted.

  When a fragrance is applied as a medicine, the air flow introduced from the air inlet 23 passes through the carrier 48 of the medicine holder 15 and passes through the wind tunnel 28 including the fragrance component, and the exhaust 16 Then, the shielding plate 17 is diffused radially toward the discharge direction, and an air flow containing the fragrance is drifted in a space such as a room in a radially diffused state.

As described above, according to the first reference example , the exhaust port 16 is disposed on the front surface of the airflow diffusion device body 11 and the intake port 23 is disposed on the back surface of the airflow diffusion device body 11. A shielding plate 17 having an outer diameter (outer shape) larger than the inner diameter (outer shape) of the exhaust port 16 is provided in the vicinity of the exhaust port 16 so as to cover the exhaust port 16. As a result, the airflow sucked from the intake port 23 by the negative pressure generated by driving the fan 14 is applied to the medicine holder 15, and as a result, the airflow containing the medicine is released from the exhaust port 16. However, at this time, due to the presence of the shielding plate 17 having an outer shape larger than the outer shape of the exhaust port 16, the air flow from the fan 14 is diffused radially toward the discharge direction without flowing substantially linearly. Since the airflow containing the medicine can be drifted over a wide range in front of the exhaust port 16, the diffusibility of the apparatus can be improved. Further, since the shielding plate 17 is provided in front of the exhaust port, internal structures (for example, the fan fixing portion 29, the fan 14, the lead wire 38, etc.) are not visible from the exhaust port 16, and the appearance is improved. There is no loss. In addition, the presence of the shielding plate 17 can suppress contact with foreign matter (for example, the fan 14, the lead wire 38, etc.) disposed in the vicinity of the exhaust port 16, so that, for example, an infant or the like mistakes a finger or the like. Therefore, safety can be improved.
Even if the shielding plate 17 is provided so as to be substantially the same as the inner diameter of the exhaust port 16, the object of the present invention can be achieved.

Further, according to the first reference example , since the medicine holder 15 is arranged on the back side of the fan 14, the medicine holder 15 is arranged on the side of the airflow diffusion device main body 11 that cannot be seen from the front side. The decorativeness can be improved. In addition, when the medicine holder 15 is periodically replaced, the rear case 13 is removed from the front case 12, but compared to the front where the shielding plate 17 is provided, that is, when the front case 12 is provided, The airflow diffusing device 10 can be a simple structure without having a complicated structure, and the handleability can be improved.

(Second reference example)
Next, a second reference example of the air flow diffusion device according to the present invention will be described with reference to FIG.
FIG. 5 is an exploded perspective view of the air flow diffusion device according to the second reference example of the present invention.
In the second reference example below, the description of the components common to the first reference example described above is simplified or omitted by attaching the same reference numerals or equivalent reference numerals.

As shown in FIG. 5, the airflow diffusion device 60 according to the second reference example has an airflow diffusion device main body 11 including a front case 12 and a rear case 13, and the rear case 13 has a horizontal slit shape. A rear cover 61 having a plurality of air inlets 23 is detachably attached, and the rear case 13 has a structure of a partition wall. In the airflow diffusing device 60, the fan 14 is disposed on the left side of the airflow diffusing device main body 11, and the operation unit 42 and indicator lamps 43 and 44 are disposed on the upper part of the front case 12.

The rear cover 61 is formed in a plate shape having an outer shape smaller than that of the rear case 13, has three locking protrusions 62 and one flexible locking piece 63, and has a stand 64 at the lower part on the back side. Have The three locking projections 62 and the one flexible locking piece 63 are locked to an engaging portion (not shown) formed on the back side of the rear case 13 so that the rear cover 61 is rear case. 13 is attached. Moreover, since the stand 64 is assembled | attached to the rear surface cover 61 so that expansion | deployment is possible, the airflow diffusion apparatus 60 can be stood up by rotating and pulling out at the time of use.
In the second reference example , instead of the medicine holder 15, a cartridge 65 having a filter 68 for purifying the airflow by filtering and removing dust and the like contained in the airflow is attached.
The filter 68 has an outer shape of 60 × 60 × 10 mm, a cell size of 2.1 mm, and a paper basis weight of 50 g / m ² and is formed in a honeycomb structure.
In this embodiment, the filter 68 that filters and removes dust and the like contained in the airflow is used. Instead, a filter that removes malodor contained in the airflow may be used, and both of them may be used. It is good also as a filter which has a function.

Since the air flow diffusing device 60 of the second reference example has the same effects as those of the first reference example , description thereof is omitted. In particular, in the case of the second reference example , instead of the medicine holder 15. The cartridge 65 having the filter 68 is applied, so that the airflow diffusion device 60 of the second reference example functions as an air cleaning device. In other words, according to the air flow diffusing device 60 according to the second reference example , the air introduced from the air inlet 23 by the negative pressure generated by driving the fan 14 passes through the filter 68 and is purified to be inside the wind tunnel portion 28. And is diffused radially from the exhaust port 16 to the shielding plate 17 in the discharge direction, and cleans in a small space such as a toilet, a tabletop, a room, a chest, a car interior, a tent, etc. over a wide range of this predetermined space. A drifted airflow will drift.
Even in the second reference example , the object of the present invention can be achieved even if the shielding plate 17 is provided so as to be substantially the same as the inner diameter of the exhaust port 16.

Next, a modified example of the filter will be described.
For the filter, a honeycomb structure in which a photocatalyst such as fine titanium oxide, a polyphenol such as ginkgo biloba extract, green tea catechin, or a natural deodorant component such as a flavonoid is mixed, impregnated, or the like is used. Can do. Further, another filter may be laminated on the honeycomb structure, and for example, a honeycomb structure, a net structure, a sheet-like structure, a nonwoven fabric structure, a laminated structure, or the like can be adopted as another filter. Furthermore, as the honeycomb structure, an oblique honeycomb structure can also be used, so that the cell wall surfaces intersect diagonally with respect to the passage direction of the airflow generated by the fan provided in the airflow diffusion device. The amount of contact between the airflow and the cell wall surface can be increased. As a result, it is possible to increase the amount of adsorption of dust, malodor, etc., or increase the volatilization amount of the active ingredient from the medicine.

(Embodiment)
Next, with reference to FIG.6 and FIG.7, embodiment of the airflow diffusion apparatus which concerns on this invention is described.
6 is a perspective view seen from the front side of the air flow diffusion device according to the embodiment of the present invention, and FIG. 7 is an exploded perspective view seen from the back side.
In the following embodiments , the description of the components common to the first reference example and the second reference example described above will be simplified or omitted by attaching the same reference numerals or equivalent reference numerals.
A rear case 13 is attached to the rear surface side of the main body 11 of the airflow diffusing device 70 in a state where the medicine holder 15 is held by the holding member 71, and a front case 12 is attached to the front side of the main body 11. An intake port 23 is formed in the rear case 13. The main body 11 is provided with a fan 14, and a battery for driving the fan 11 is accommodated in a lower portion of the main body 11, and the battery is covered with a bottom cover 72.

The front case 12 is formed with a plurality of exhaust ports 16, and a shielding plate 17 is attached to a portion (substantially central portion of the front case 12) located substantially in front of the fan 14 and the medicine holder 15.
According to the present embodiment, the airflow containing the medicine is released from the exhaust port 16. At this time, the airflow from the fan 14 does not flow substantially linearly due to the presence of the shielding plate 17. Diffused. As a result, since the air flow containing the medicine can be drifted over a wide range in front of the exhaust port 16, the diffusibility of the apparatus can be improved. Further, since the shielding plate 17 is provided at the substantially central portion of the front case 12, the internal structure cannot be seen from the front through the exhaust port 16, and the appearance is not impaired. In addition, the presence of the shielding plate 17 can improve safety because, for example, an infant or the like does not accidentally insert a finger or the like.

  Next, the Example performed in order to confirm the effect of the airflow diffusion apparatus which concerns on this invention is described.

Example 1
The characteristics of the shielding plate 17 were tested by setting the distance between the shielding plate 17 disposed in front of the exhaust port 16 and the fan 14 to four different values and measuring their air volumes. The test results are shown in Table 1.
In addition, the apparatus 10 of FIG. 1 was used as an airflow diffusion apparatus. That is, the diameter of the swirl vane 34 is 59 mm, 11 blades, the outer shape of the carrier 48 of the medicine holder 15 is 60 × 60 × 10 mm, the cell size is 2.1 mm, and the paper basis weight is 50 g / m ^2. The test was carried out with the honeycomb structure and the applied voltage of the DC brush motor 33 set to 3.0 V and the rotation speed set to about 1100 rpm.
For measuring the air volume, a cylindrical body having a substantially rectangular cross section is applied from the rear so as to cover the entire air inlet 23, and the wind speed is applied to an intermediate portion inside the cylindrical body (about 40 cm from the airflow diffusion device main body). Two measuring terminals are installed at different heights, and after 2 minutes, the numerical values indicated by the two sets of wind speed measuring terminals are confirmed five times at predetermined time intervals (15 seconds), and the average value is obtained. Expressed as air volume.

  As is clear from Table 1, in Comparative Examples 1 and 2 where the separation distance between the shielding plate and the fan is 17 mm and 22 mm, the air volume is almost 10% compared to Examples 1 and 2 where the separation distance is 7 mm and 12 mm. Declined. Thus, it was found that by setting the shielding plate 17 and the fan 14 to a separation distance L3 of 7 mm to 12 mm, appropriate drug diffusion can be obtained without impairing the air volume.

Example 2
Using the airflow diffusing device having the configuration shown in FIG. 1, the chemical was volatilized in the test room to examine the control effect against mosquitoes.

  As an example of the present invention, an air flow diffusion device having the configuration shown in FIG. 1 (the same as that of Example 1) was used, and “No battery 90 days set with battery” manufactured by Earth Pharmaceutical Co., Ltd. was used as a comparative example. As the drug holder, the same examples and comparative examples were used. This drug holder is obtained by impregnating and holding 1100 mg of a mixed solution of 500 mg of transfluthrin and 600 mg of liquid paraffin in a pulp carrier having a honeycomb structure of 60 mm × 60 mm × 10 mm.

  The test room was a 10 tatami room (4.5 m × 3.6 m, height 2.4 m) adjusted to a humidity of 60-80% RH and a temperature of 27 ± 2 ° C. Then, as shown in FIG. 8, 17 female mosquitoes of Culex mosquito were placed in each cage and hung diagonally at positions 90 cm horizontal from the wall and 75 cm and 150 cm high from the floor. Here, the horizontal distance from the center of the test chamber to each cage is about 1.4 m. And the chemical | medical agent was spread | diffused by placing the air flow diffusion apparatus of the Example of this invention in the center of the test room. In addition, the airflow diffusing device of the example and the comparative example placed the front surface provided with the exhaust port so as to face a predetermined wall surface (A in FIG. 8).

Activate the air flow diffuser and count the number of squid cuts in each cage every 10 minutes from the start of the test, KT50 (50% knockdown time (minutes)), KT90 (90% knockdown time (minutes) )) Was calculated.
Counting was continued for 2 hours, after which each cage was taken out of the test room, the squid was transferred to a clean cup and allowed to stand at a temperature of 27 ± 2 ° C., and the mortality after 24 hours was calculated.
The results are shown in Table 2.

As shown in Table 2, KT50 at a height of 75 cm showed substantially the same effect, but at a height of 150 cm, the KT50 was faster in the examples of the present invention and the diffusion of active ingredients was excellent. It became clear. In KT90, the same tendency was shown.
From these results, there is no difference in the amount of air generated by the fan and the amount of volatilization of the active ingredient from the medicine holder between the example of the present invention and the comparative example, but a predetermined shielding plate is located in front of the exhaust port. It has been clarified that the arranged embodiment of the present invention is superior in diffusibility of the active ingredient to a distant place due to its structure.

As shown in FIG. 9, the two Acrylic containers (30 cm × 30 cm × 30 cm) are combined, and the airflow diffusion device of the embodiment shown in FIG. In between, it was installed densely by an acrylic plate so that there was no movement of air. Then, the air flow diffusing device was operated so that air flow was generated from the container A toward the container B, and 0.2 g of dust was sprayed with the syringe to fill the container A corresponding to the air inlet side of the air flow diffusing device.
The air flow diffusion device was operated for 30 minutes, and the dust concentration was measured over time from the sampling port of the container B using a light scattering digital dust meter MODEL3431 (manufactured by Nippon Kanomax).
