Hereinafter, a drug diffusion device according to an embodiment of the present invention will be described as a drug diffusion device for diffusing a drug for removing or killing insects such as mosquitoes and moths.
FIG. 1 is a perspective view of a drug diffusing apparatus according to an embodiment of the present invention with a lid closed, FIG. 2 is a schematic perspective view of a state in which the lid is opened and no assembly is attached, and FIG. FIG. 4 is a perspective view showing the assembled state of the assembly, FIG. 4 is a perspective view showing a state where the assembly is mounted on the battery storage box from above, and FIG. 5 is a longitudinal sectional view of FIG.

  As shown in these figures, the drug diffusing device 1 includes a diffusing device body 2 having a drug, a drive motor 3, batteries (alkali dry batteries) 4 and 4 for supplying power to the drive motor 3, and a drug. The medicine holder 5 is provided.

The diffusion device main body 2 is formed in a hollow box shape (a rectangular parallelepiped shape) with the top opened. A drive motor 3 is housed and fixed inside the diffusion device body 2. The drive motor 3 is housed in a box 6, and its motor shaft 7 is located at the center of the diffusion device body 2 and protrudes from the box 6 in parallel (perpendicular) to the frame-like side wall 8 of the diffusion device body 2. .
On both sides of the box body 6, a box-shaped battery storage portion 11 having an open portion 10 at the top is arranged. That is, the battery storage unit 11 is composed of a pair of battery storage boxes 12 and 12 that are separated via the box 6. The side walls of the battery storage boxes 12, 12 are installed so as to fit into the side walls 8 of the diffusion device body 2. The battery storage boxes 12 and 12 are formed in a rectangular parallelepiped shape.

  A lid 14 covering the open surface of the diffusion device body 2 is attached to the side wall 8 of the diffusion device body 2 via a first hinge 13 so as to be freely opened and closed. The lid body 14 is formed with a dome portion 16 having a lead-out hole 15 for leading the medicine into the atmosphere.

As shown in FIG. 3 and FIG. 4, the batteries 4 and 4 and the disc-shaped drug holding body 5 are set as an assembly 17 so that they can be handled as an integrated body. That is, the assembly 17 is a plate-like shape that connects the batteries 4 and 4, a pair of battery holders 18 and 18 that hold the batteries 4 and 4, and the upper surfaces of the battery holders 18 and 18. The connecting member 20, the drug holding body 5, and a plurality of support legs 21 that support the drug holding body 5 in a floating state with respect to the connecting member 20.
Here, the batteries 4 and 4 are accommodated in the battery holders 18 and 18 in a normal direction (a positive electrode and a negative electrode are in the correct direction). This can prevent the user from installing the batteries 4 and 4 in the wrong direction (the direction in which the positive electrode and the negative electrode are reversed).

  The battery holders 18 and 18 are formed in a relative shape with the battery storage boxes 12 and 12 so as to be fitted into the battery storage boxes 12 and 12 from above. The battery holders 18 and 18 are spaced apart in the radial direction of the batteries 4 and 4.

  The connecting member 20 is formed in a disc shape, and both sides of the outer peripheral portion thereof are fixed to the upper surfaces of the battery holders 18, 18. With this configuration, the battery holders 18, 18 are integrated. The battery holders 18, 18, the connecting member 20, and the support legs 21 are made of a synthetic resin material.

  At least three support legs 21 are provided on the outer periphery of the connecting member 20 at predetermined intervals. The bases of these support legs 21 are formed integrally with the connecting member 20 and are provided so as to be tilted outward in the radial direction of the connecting member 20 around the base.

Each support leg 21 is integrally formed with a support leg main body 22 and holding body support pieces 23 and 24 separated from each other in the length direction of the support leg 21 by approximately the thickness of the drug holding body 5.
The holding body support pieces 23 and 24 stand with the support leg main body 22 in a standing state, that is, the support leg main body 22 is slightly inclined outward in the radial direction with respect to the direction along the central axis of the connecting member 20. In the state, it protrudes inward in the radial direction of the connecting member 20.
That is, each support leg 21 has a diameter of a virtual circle connecting the opposing surfaces of the support leg main body 22 in the vicinity of the lower support body support pieces 23 and 24 substantially equal to the diameter of the medicine holder 5. The diameter of the imaginary circle connecting the opposing surfaces of the support leg main body 22 at the base is preferably set smaller than the diameter of the medicine holder 5.

The drug holding body 5 includes a holding frame member 25 and a drug impregnated body 26 that is fitted and held inside in the radial direction of the holding frame member 25. The holding frame member 25 is formed from a hard synthetic resin, and the drug impregnated body 26 is formed from a three-dimensional network so that the drug can be impregnated.
The configuration of the holding frame member 25 is not particularly limited as long as the medicine impregnated body 26 can be reliably attached and the upper part is opened.

  In the figure, the holding body support pieces 23 and 24 are drawn with exaggerated thickness, but at least the lower holding body support piece 23 has its elasticity set so that it can be easily bent by the pressing force from above. Specifically, by forming the thickness thin, when the holding frame member 25 is pressed from above, the holding frame member 25 can be easily bent downward and the holding frame member 25 can be pushed down.

  At the center of the holding frame member 25 and the drug impregnated body 26, shaft holes 27 and 28 into which the motor shaft 7 is inserted are formed. The shaft hole 27 of the holding frame member 25 is substantially the same as the diameter of the motor shaft 7 and has a smaller diameter than the shaft hole 28 of the drug-impregnated body 26.

  In addition, on the upper part of the holding frame member 25, locking pieces 30 that prevent the holding frame member 25 from coming off after the drug-impregnated body 26 is attached to the holding frame member 25 are integrally formed at a plurality of locations. Further, when the holding frame member 25 is pushed down, a pressing piece (not shown) is provided by extending the shaft hole 27 at the upper center of the holding frame member 25 so that the user's finger does not touch the drug impregnated body 26. The presser piece is preferably configured to be pushed down with fingers.

  A procedure for mounting the assembly 17 to the diffusion device main body 2 in the above configuration will be described. First, the user of the drug diffusing device 1 rotates the lid 14 of the diffusing device body 2 around the first hinge 13 to open the upper portion of the diffusing device body 2 to expose the motor shaft 7.

  Next, the user holds the assembly 17 with his / her fingers and holds the battery holders 18, 18 from above, that is, from the axial direction of the motor shaft 7 in order to mount the batteries 4, 4 in the battery housing 11. The battery storage portion 11 is inserted into this as a guide. Then, since the medicine holder 5 is supported by each support leg 21 and floats from the connecting member 20, the motor shaft 7 and the shaft holes 27 and 28 face each other in the vertical direction.

In such a state, the medicine holder 5 is pressed downward. Then, when the holding body support pieces 23 and 24 are bent downward by the holding frame member 25 of the drug holding body 5 and further pressed, the diameter of the virtual circle connecting the opposing surfaces at the base of the support leg main body 22 is the drug holding Since it is set to be smaller than the diameter of the body 5, the support leg main body 22 falls radially outward from its base, and the motor shaft 7 is fitted into both the shaft holes 27 and 28.
Further, the drive motor 3 is arranged between the battery holders 18 and 18.

Then, the user closes the lid body 14 around the first hinge 13. Since the motor shaft 7 and the drug holding body 5 (drug-impregnated body 26) are integrated as described above, the drug-impregnated body 26 is rotated about the axis by the rotation of the motor shaft 7, that is, the drive motor 3. The drug is diffused (volatilized) from the drug-impregnated body 26 into the atmosphere by the airflow (wind force) generated during the rotation.
If the support leg 21 is in the way after the medicine holder 5 is attached to the diffusion device main body 2, the user can remove it by cutting it off.

  As described above, according to the embodiment of the present invention, the batteries 4 and 4 and the drug holding body 5 can be handled as one unit as the assembly 17, or the user can use the batteries 4 and 4 and the drug holding body 5. Since the assembly 17 is configured so that the power of the batteries 4 and 4 and the life of the medicine match, the battery 4 and 4 have a lot of power remaining. Inconveniences such as no medicine or a remaining amount of battery power even though a lot of medicine remains can be solved.

  The used assembly 17 can be easily obtained by the user opening the lid 14 around the first hinge 13 and pulling out the medicine holder 5 and the battery holders 18 and 18 in the axial direction of the motor shaft 7. Can be removed.

  Another embodiment of the present invention will be described with reference to FIGS. 6 is an overall perspective view of a state in which the assembly 17 of the drug diffusing apparatus 1 according to another embodiment is not attached, and FIGS. 7A and 7B are perspective views showing the entire configuration of the assembly 17. 8 is a perspective view in which the diffusion device main body 2 is omitted when the assembly 17 is mounted toward the drive motor 3 and the battery holders 18 and 18 side, FIG. 9A is a plan view, and FIG. It is a side view similarly.

  The drug diffusing device 1 in the embodiment shown in FIGS. 6 to 9 is for mounting the assembly 17 on the diffusing device main body 2 from the radial direction of the motor shaft 7.

  The lid body 14 of the diffusing device body 2 includes a dome portion 16 and a rectangular plate-like lid portion 35 formed separately. The lid portion 35 is attached to the side wall 8 through a second hinge 36 different from the first hinge 13 so as to be openable and closable, and an insertion hole 37 into which the motor shaft 7 is inserted is formed at the center.

  A side wall portion 38 is provided at a lower portion of the opposite side wall portion 38 of the side wall 8 to which the first hinge 13 is attached via a third hinge 40 having an axis parallel to the first hinge 13 so as to be opened and closed. Yes.

  The side walls 38 of the battery storage boxes 12, 12 are open. With this configuration, the assembly 17 can be attached to the diffusion device body 2 from the radial direction of the motor shaft 7.

  That is, the assembly 17 includes the batteries 4 and 4, the battery holders 18 and 18 that are connected by the plate-like connecting member 20 so as to be separated in parallel in the radial direction of the batteries 4 and 4, the medicine holder 5, and the medicine And a holder 41 as support means for mounting the holding body 5. The holder 41 is rotatably supported by the connecting member 20 via the fourth hinge 43.

  The connecting member 20 has a rectangular plate shape. A motor shaft insertion recess 44 parallel to the batteries 4 and 4 is formed in the center of the side portion of the connecting member 20. The motor shaft insertion recess 44 extends from the side end face 20 a of the connecting member 20 to a position that is substantially half the length of the battery holders 18, 18. The side end face 20a of the connecting member 20 is arranged so as to be displaced in the length direction from the end faces 18a of the battery holders 18 and 18.

  The holder 41 has a configuration in which a pair of semi-disc-shaped counter plates 45 and 46 are provided in parallel and connected by a plurality of connecting pieces 47, and the diameter of the counter plates 45 and 46 is larger than the diameter of the drug holding body 5. Is set large. The spacing between the opposing plates 45 and 46 is set larger than the thickness of the medicine holder 5. In a state where the medicine holder 5 is mounted on the holder 41, the shaft hole 28 is exposed without being covered by the opposing plates 45 and 46 of the holder 41. Then, the motor shaft insertion recess 44 and the shaft hole 28 are in a position coincident with each other in the axial direction in a state where the medicine holder 5 is mounted on the holder 41.

The end center of one (lower) opposing plate 46 and the central part of the side end face 20 b of the connecting member 20 are connected by the fourth hinge 43.
The fourth hinge 43 is formed of a single flexible resin plate, one end of which is fixed to the holder 41, that is, one of the opposing plates 46, and the other end is fixed to the connecting member 20. . The fourth hinge 43 has flexibility and allows the holder 41 to move along the surface of the connecting member 20 by the flexibility.

  In the above configuration, the lid portion 35 is closed, the motor shaft 7 is projected from the insertion hole 37 of the lid portion 35, the side wall portion 38 is rotated around the third hinge 40, and the opening 38a covered with the side wall portion 38 is opened. Keep it. On the other hand, the assembly 17 holds the medicine holder 5 in the holder 41, and when the holder 17 is mounted on the diffusion device body 2, the holder 41 is rotated around the fourth hinge 43 to connect the connecting member 20. The battery holders 18 and 18 are inserted from the opening 38a (from the radial direction of the motor shaft 7).

Then, since the side wall portion 38 side of the battery storage boxes 12 and 12 is opened, the battery holders 18 and 18 are easily inserted into the battery storage boxes 12 and 12 using the battery storage boxes 12 and 12 as a guide.
Further, the drive motor 3 is arranged between the battery holders 18 and 18.

Subsequently, the holder 41 is tilted around the fourth hinge 43 and the shaft hole 28 is inserted and fitted into the motor shaft 7. In this case, since the holder 41 is tilted around the fourth hinge 43, the shaft hole 28 is not necessarily inserted smoothly from the axial direction of the motor shaft 7. Even in such a case, the fourth hinge 43 allows the holder 41 to move along the surface of the connecting member 20 due to its flexibility. Therefore, the holder 41 can be moved along the surface of the connecting member 20. By moving, the shaft hole 28 can be aligned with the motor shaft 7 in the axial direction, and the shaft hole 28 can be inserted into the motor shaft 7 from the axial direction. At this time, the holder 41 is positioned above the lid portion 35.
In addition, when the part which the holder 41 covers the chemical | medical agent holding body 5 is large, it may affect the spreading | diffusion state of a chemical | medical agent, Therefore It is preferable to design so that a covering area may be made as small as possible or it pulls out after mounting | wearing with the assembly 17.

  After the assembly 17 is mounted on the diffusion device main body 2 as described above, the dome portion 16 is closed and the drive motor 3 is driven so that the spacing between the opposing plates 45 and 46 is larger than the thickness of the drug holding body 5. Therefore, the medicine holder 5 rotates smoothly together with the motor shaft 7. This allows the drug to diffuse into the atmosphere.

  Also in this embodiment, since the batteries 4 and 4 and the medicine holder 5 are handled as an integrated product 17, the battery 4 and 4 are used so that the power of the batteries and the life of the medicine coincide with each other. In other words, it is possible to eliminate the disadvantage that the batteries 4 and 4 have a large amount of power remaining and no drug is present, or that a large amount of drug remains and the battery has no remaining power.

  The used assembly 17 is removed from the motor shaft 7 by the user opening the lid 14 around the first hinge 13, turning the medicine holder 5 around the fourth hinge 43, and removing the battery holder 18. , 18 can be easily removed by pulling them out into the opening 38a (in the radial direction of the motor shaft 7).

  As the supporting means, the one shown in FIG. 10 can be considered. This is because the support leg 21 is integrally formed from a support leg main body 22 and holding body support pieces 23 and 24 separated from each other in the length direction of the support leg 21 by approximately the thickness of the drug holding body 5 at the upper part thereof. On the other hand, a plurality of support legs 50 are formed in a simple thin plate shape without particularly providing the holding body support pieces 23 and 24. And the opposing surface of each support leg 50 is formed in the taper surface shape where the length direction (height direction) upper part inclines radially outward.

  The diameter of the imaginary circle connecting the opposing surfaces of the support legs 50 at the upper end in the length direction (height direction) of each support leg 50 or in the middle in the length direction is set to be approximately equal to the diameter of the medicine holder 5. The diameter of the virtual circle connecting the opposing surfaces of the support leg main body 22 at the base is set to be smaller than the diameter of the medicine holder 5. Other configurations are the same as those shown in FIG. 3, and therefore, the same reference numerals are given and description thereof is omitted.

Also with the configuration described above, the batteries 4 and 4 and the drug holding body 5 can be handled as an integrated assembly 17 in a state where the drug holding body 5 is supported by the support legs 50.
The user grasps the assembly 17 with his / her fingers and places the assembly 17 upward, that is, the battery holders 18 and 18 from the axial direction of the motor shaft 7 so as to mount the batteries 4 and 4 in the battery housing 11. The part 11 is inserted into this as a guide. Then, since the medicine holder 5 is supported by the respective support legs 50 and floats from the connecting member 20, the motor shaft 7 and the shaft holes 27 and 28 face each other in the vertical direction. In such a state, the medicine holder 5 is pressed downward. Then, each support leg 50 falls radially outward from the base by the holding frame member 25 of the medicine holder 5, and the motor shaft 7 is fitted into both the shaft holes 27 and 28. Each support leg 50 may be removed after the assembly 17 is mounted.
