Description

  The present invention relates to a medicine spraying device.

  As this kind of medicine spraying device, there is one provided with a medicine container containing a fragrance, and a drive unit (permanent magnet and electromagnetic coil) for spraying the fragrance by pendulum movement of the medicine container (patent) Reference 1).

JP 2006-68505 A

  Since the said chemical | medical agent spraying apparatus only carries out the pendulum movement of the chemical | medical agent container, the spraying efficiency of the fragrance | flavor was bad.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a drug spraying device capable of improving the spraying efficiency of the drug.

  In order to solve the above problems, the medicine spraying device of the present invention includes a blower unit capable of sending wind in a predetermined blowing direction, a first drive unit capable of driving the blower unit, and the blower. And a second drive unit capable of swinging or rotating the drug container.

  According to such an aspect of the invention, the medicine contained in the medicine container is aired by the medicine container being swung or rotated by the second driving section in the lee of the air blowing section driven by the first driving section. And spread out of the drug container. This medicine is sprayed on the wind generated in the blower. Therefore, the spraying efficiency of the medicine of the medicine spraying device can be improved. And since this chemical | medical agent spraying apparatus is a structure which a chemical | medical agent container rocks | fluctuates or rotates in the lee of a ventilation part, it can make it difficult for a chemical | medical agent container to block the wind which generate | occur | produced in the ventilation part. Therefore, the external shape of the medicine container can be set to an appropriate size (larger or smaller).

  The second drive unit can be configured to be able to swing the medicine container in a direction intersecting the blowing direction of the blowing unit. The drug container includes first and second end portions in the swing direction of the drug container, and an inclined portion that is provided at at least one of the first and second end portions and is inclined upward in the blowing direction. It is possible to have a configuration having.

  In the case of such an aspect of the invention, the inclined portion that is inclined upward in the blowing direction of the medicine container changes the direction of the wind generated in the blowing section from the blowing direction to the conversion direction intersecting the blowing direction by the swing of the medicine container. Since it can be changed, it is possible to improve the spraying efficiency of the medicine of the medicine spraying apparatus. In addition, since the blower unit and the medicine container can be arranged vertically (in the vertical direction), the horizontal projection area of the medicine spraying device can be reduced.

  The medicine spraying device may be configured to further include a case in which at least the first and second driving units are accommodated and the medicine container is partially accommodated. The case is provided on the lee of the air blowing portion of the case, the drug container partially protrudes outside the case, and an opening having a size in the swing direction larger than the swing range of the drug container. The first and second edges of the opening in the swing direction can be used. A gap is provided between the first edge and the first end of the drug container, and between the second edge and the second end of the drug container. It is possible.

  According to such an aspect of the invention, when the drug container swings, collision between the first and second end portions of the drug container and the first and second edge portions of the case is avoided. Moreover, since the opening of the case is provided in the lee of the air blowing part of the case, the wind generated in the air blowing part causes the first and second edges of the case opening and the first and second ends of the medicine container. It is discharged out of the case from the gap between the parts. For this reason, since the wind discharged from the gap passes through the vicinity of the medicine container, the medicine placed in the medicine container can be easily spread on the wind.

  The inclined portion may have a through hole that communicates with the inside and outside of the drug container. In the case of such an aspect of the invention, when the inclined portion changes the wind generated in the blowing portion from the blowing direction to the conversion direction, the drug placed in the drug container contacts the air through the through hole and diffuses outside the drug container. Therefore, it becomes easy to spread the medicine on the wind. Therefore, the spraying efficiency of the medicine of the medicine spraying device can be improved.

  The first and second driving units may be a single motor having first and second rotating shafts. The air blowing unit may be a fan connected to the first rotating shaft. The medicine spraying device may further include a motion transmission unit having a swinging member to which the medicine container is connected. The motion transmission unit may be configured to convert the rotation of the second rotation shaft into the swing of the swing member and transmit it to the drug container.

  According to such an aspect of the invention, since the first and second drive units are configured by a single motor, the number of parts of the medicine spraying device can be reduced, and the cost can be reduced. It is. The first driving unit may be a motor having a first rotating shaft, and the second driving unit may be a motor having a second rotating shaft.

  The motion transmission unit may further include at least one of a gear mechanism, a link mechanism, and a cam mechanism that converts the rotation of the second rotation shaft into the swing of the swing member.

  The gear mechanism may be a reduction gear mechanism that decelerates the rotation of the second rotation shaft. In the case of such an aspect of the invention, the motion transmission unit converts the rotation of the second rotating shaft decelerated by the reduction gear mechanism into the swing of the swing member, so that the swing of the swing member Can be made slower than the rotation speed of the second rotating shaft. By setting the reduction gear mechanism, it is possible to optimize the amount of diffusion of the medicine placed in the medicine container.

  The medicine spraying device may further include a box that accommodates the motion transmission unit. The swing member includes a first end connected to the drug container, a second end connected to at least one of the gear mechanism, a link mechanism, and a cam mechanism, and the first and second ends. It is possible to make it the structure which has a shaft support part provided in between and supported by the said box.

  According to such an aspect of the invention, since the pivot support portion of the swing member is pivotally supported by the box, the swing range of the first end portion of the swing member is reduced. Therefore, it is possible to reduce the size of the medicine spraying device.

The first rotation shaft 210 protrudes from the center of the drive unit 200 to one side and can rotate in the rotation direction D4 according to the drive of the drive unit 200. The second rotating shaft 220 protrudes from the center of the driving unit 200 to the other side and can rotate at the same rotational speed in the same direction as the first rotating shaft 210 according to the driving of the driving unit 200.

  As shown in FIGS. 2A to 3B, the air blower 100 is a rotary fan. The blower unit 100 includes a circular cup 110, a connection unit 120, and a plurality of blades 130. The cup 110 has a disk and a peripheral wall that is erected on the peripheral edge of the disk. The inner diameter of the peripheral wall is larger than the outer diameter of the drive unit 200. The drive unit 200 is accommodated in the cup 110. A cylindrical connection 120 is provided at the center of the disc of the cup 110. The inner diameter of the connecting part 120 is substantially the same as the outer diameter of the first rotating shaft 210 of the driving part 200. The first rotating shaft 210 of the drive unit 200 is fitted in the connection unit 120. For this reason, the ventilation part 100 can rotate in the rotation direction D4 according to rotation of the 1st rotating shaft 210 of the drive part 200. FIG. The blades 130 are provided on the peripheral wall of the cup 110 with an interval in the rotation direction D4. The blades 130 are inclined downward in the direction opposite to the rotation direction D4. When the air blowing unit 100 rotates in the rotation direction D4, the upper air is taken in by the blades 130 and is sent to the lower side (air blowing direction D1).

  The box 500 is a box that accommodates the motion transmission unit 400 and supports the driving unit 200. The box 500 includes cup-shaped first and second boxes 510 and 520 that are combined with each other. The first box 510 has a pedestal 511 and an opening 512. The pedestal 511 is a disk-shaped pedestal provided at the upper end of the first box 510. The drive unit 200 is installed on the pedestal 511. As shown in FIG. 2B, a circular hole 511a is provided at the center of the base 511. The second rotating shaft 220 of the driving unit 200 is inserted into the hole 511a. The opening 512 is opened at the lower end of the first box 510.

  The second box 520 has openings 521 and 522 and slits 523, 524 and 525. As shown in FIGS. 2A and 3A, the opening 521 is a semicircular hole provided in the upper end portion of the second box 520 and is closed by the base 511. As shown in FIG. 3A, the opening 522 is opened at a location corresponding to the opening 512 at the lower end of the second box 520. The openings 522 and 512 are combined to form a rectangular lead-out hole. The slit 523 is a rectangular hole provided at one end of the second box 520 in the swing direction D2. As shown in FIG. 3B, the slit 524 is a rectangular hole provided at the other end of the second box 520 in the swing direction D2. As shown in FIG. 2A, the slit 525 is a rectangular hole provided adjacent to the slit 524 at the other end of the second box 520 in the swing direction D2. The slits 524 and 525 communicate with each other. The dimension (length dimension) of the slit 525 in the blowing direction D1 is smaller than the dimension (length dimension) of the slit 524 in the blowing direction D1.

  As shown in FIGS. 2A, 2B, and 3C, the motion transmission unit 400 includes a reduction gear mechanism and a link mechanism. The reduction gear mechanism includes a worm gear 410, a worm wheel 420, and a gear 430. The worm gear 410 is fitted on the second rotation shaft 220 of the drive unit 200 and can rotate in the rotation direction D4 together with the second rotation shaft 220.

  The worm wheel 420 includes a circular large-diameter gear 421 and a circular small-diameter gear 422 whose outer diameter is smaller than that of the large-diameter gear 421. The small diameter gear 422 is provided on one surface of the large diameter gear 421 in the width direction. The center of the small diameter gear 422 and the center of the large diameter gear 421 coincide. The central part of the worm wheel 420 (the central part of the large diameter gear 421 and the small diameter gear 422) is pivotally supported by the first box 510, and the groove on the outer peripheral surface of the large diameter gear 421 is engaged with the worm gear 410. Thus, the worm wheel 420 (that is, the large diameter gear 421 and the small diameter gear 422) can rotate in a direction (vertical direction) perpendicular to the rotation direction D4 according to the rotation of the worm gear 410.

  The gear 430 is a circular gear having an outer diameter larger than the outer diameter of the large diameter gear 421. The center portion of the gear 430 is pivotally supported by the first box 510, and the groove on the outer peripheral surface of the gear 430 is engaged with the small diameter gear 422. Thus, the gear 430 can rotate in the same direction as the small diameter gear 422 in accordance with the rotation of the small diameter gear 422. A part of the gear 430 projects out of the second box 520 from the slit 524 of the second box 520. As described above, the reduction gear mechanism reduces the speed by converting the rotation of the second rotating shaft 220 of the drive unit 200 (the rotation of the worm gear 410) to the rotation of the gear 430 having a large outer diameter. The load on the second rotating shaft 220 of the drive unit 200 is reduced by the reduction gear mechanism.

  The link mechanism includes a link rod 440 that is a linear long plate and a swing member 450 that is a substantially L-shaped plate. The link rod 440 has a first end 441 in the length direction and a second end 442 in the length direction. The swing member 450 includes a first end portion 451 in the length direction, a second end portion 452 in the length direction, a shaft support portion 453, and a shaft portion 454. A first end 441 of the link rod 440 is rotatably connected to one surface in the width direction of the gear 430. The second end 442 of the link rod 440 is rotatably connected to the second end 452 of the swing member 450. The pivot support 453 of the swing member 450 is pivotally supported by the first box 510 in the vicinity of the upper side of the opening 512 of the first box 510. In response to the rotation of the gear 430, the link rod 440 turns in the rotation direction of the gear 430 with the first end 441 as a fulcrum. As a result, the second end 452 of the swing member 450 swings in the swing direction D2, and the first end 451 of the swing member 450 swings in the swing direction D2 with the shaft support 453 as a fulcrum.

  It should be noted that the second end 442 of the link rod 440 and the second end 452 of the swing member 450 are on the left side of FIG. 2A to avoid interference between the swinging second ends 442 and 452 and the second box 520. For this purpose, a slit 523 is arranged. The first end 451 of the swing member 450 protrudes outside the first and second boxes 510 and 520 from the openings 512 and 522 (leading holes of the box 500) of the first and second boxes 510 and 520. The size of the opening 512, 522 in the swing direction D2 is set to be larger than the swing range of the first end 451 of the swing member 450. For this reason, when the first end 451 of the swinging member 450 swings, interference between the edge of the opening 512, 522 in the swinging direction D2 and the first end 451 of the swinging member 450 is avoided. .

  The shaft portion 454 is a columnar bar provided at the first end 451 of the swing member 450. The shaft portion 454 extends in an orthogonal direction D5 orthogonal to the air blowing direction D1 and the swinging direction D2.

  The drug container 300 is a box that can store a drug such as a fragrance. The medicine container 300 has a rectangular bottom plate, first and second end portions 310 and 320 in the swing direction D2, and third and fourth end portions 330 and 340 in the orthogonal direction D5. The first and second end portions 310 and 320 are erected on the end portion of the bottom plate in the swing direction D2. The third and fourth end portions 330 and 340 are erected on the end portion in the orthogonal direction D5 of the bottom plate.

  The first, second, third, and fourth end portions 310, 320, 330, and 340 each have an upper end portion that extends in the blowing direction D1 (vertical direction) and a lower end portion. Long holes 311 and 321 extending in the orthogonal direction D5 are provided at the upper ends of the first and second end portions 310 and 320, respectively. Long holes 331 and 341 having the same shape as the long holes 311 and 321 and extending in the swinging direction D2 are provided at the upper ends of the third and fourth end portions 330 and 340. The long holes 331 and 341 include a small-diameter hole having substantially the same inner diameter as the shaft portion 454 of the swing member 450 and a large-diameter hole that is continuous with the small-diameter hole and has a larger inner diameter than the small-diameter hole. The small diameter holes of the long holes 331 and 341 are opposed to each other. The large-diameter hole of the long hole 331 is disposed on one side of the swing direction D2 of the small-diameter hole of the long hole 331. The large-diameter hole of the long hole 341 is disposed on the other side of the swing direction D2 of the small-diameter hole of the long hole 341. The shaft portion 454 of the swinging member 450 is inserted into the large-diameter holes of the long holes 331 and 341, and the drug container 300 is twisted in the rotation direction D4, whereby the shaft portion 454 is fitted into the small-diameter holes of the long holes 331 and 341. Match. When the medicine 300 is twisted in the direction opposite to the rotation direction D4, the shaft portion 454 and the small diameter holes of the long holes 331 and 341 are disengaged, and the shaft portion 454 of the swing member 450 is disengaged from the long holes 331 and 341. It is possible to remove from the large-diameter hole.

  Inclined portions 312, 322, 332, and 342 are provided at lower ends of the first, second, third, and fourth end portions 310, 320, 330, and 340. The inclined portions 312, 322, 332, and 342 are inclined in the air blowing direction D1. Of the inclined portions 312, 322, 332, 342, the inclined portions 312, 322 press the wind of the blowing unit 100 by the swinging of the medicine container 300, and change the direction of the wind of the blowing unit 100 from the blowing direction D <b> 1. Change to D3. The inclined portions 312, 322, 332, and 342 are provided with a plurality of through holes 350 that penetrate the inclined portions 312, 322, 332, and 342. The through hole 350 communicates the inside and outside of the drug container 300. Therefore, when the medicine container 300 swings, the medicine accommodated in the medicine container 300 comes into contact with air through the through-hole 350 and can diffuse.

  The case 600 is a robot type case as shown in FIGS. 1A and 1B. The case 600 includes a case main body 610 and a pair of support portions 620. The case main body 610 includes a cylindrical portion 611 and a dome 612 provided integrally with the upper end of the cylindrical portion 611. The box 500 is hollowly supported in the case main body 610 by a support unit (not shown), and the motion transmission unit 400 accommodated in the box 500, the driving unit 200 supported by the box 500, and the driving unit 200 are included in the case main body 610. The blower unit 100 attached to the second rotating shaft 220 is accommodated. A plurality of windows 612a are opened at intervals in the rotational direction D4 in a portion around the air blowing unit 100 of the dome 612. Air outside the case body 610 is taken into the case body 610 through the window 612a.

  The cylindrical portion 611 includes a substantially rectangular opening 611a provided on the lee of the air blowing portion 100 of the case body 610, first and second edge portions 611a1 and 611a2 in the swing direction D2 of the opening 611a, and an orthogonal direction D5. And third and fourth edges. The opening 611a is opened at the lower end of the cylindrical portion 611. The dimension of the opening 611a in the swing direction D2 (the distance between the first and second edge portions 611a1 and 611a2) is larger than the swing range of the upper end portion of the drug container 300. The dimension of the opening 611a in the orthogonal direction D5 (the distance between the third and fourth edges) is larger than the dimension of the upper end portion of the drug container 300 in the orthogonal direction D5. The drug container 300 is suspended from the first end 451 of the swinging member 450, and the upper end (the first, second, third, and fourth ends 310, 320, 330, and 340 of the drug container 300 is suspended. The upper end portion) is accommodated in the case main body 610 through the opening 611a. In other words, the inclined portions 312, 322, 332, and 342 of the medicine container 300 protrude from the case body 610 through the opening 611 a.

  A first gap S1 is formed between the first edge portion 611a1 and the upper end portion of the first end portion 310 of the medicine container 300. A second gap S2 is formed between the second edge 611a2 and the upper end of the second end 320 of the medicine container 300. A third gap is formed between the third edge and the upper end of the third end 330 of the medicine container 300. A fourth gap is formed between the fourth edge and the upper end of the fourth end 340 of the drug container 300. The first to fourth gaps are located leeward of the air blowing unit 100. Therefore, the wind generated in the blower 100 can be discharged out of the case body 610 through the first and second gaps S1 and S2 and the third and fourth gaps. Since the wind of the air blowing unit 100 is discharged from the first and second gaps S1 and S2 in this way, the wind passes in the vicinity of the inclined portions 312 and 322. The efficiency of converting the direction of the wind from the blowing direction D1 to the conversion direction D3 is improved.

  As shown in FIG. 1A, the support portions 620 are provided at both ends of the case body 610 in the orthogonal direction D5 and support the case body 610 in a hollow state. As shown in FIG. 1B, each support portion 620 is provided with a housing recess 621 that houses the battery 700. The battery 700 is connected to the control unit and the drive unit 200 by a cable or the like (not shown).

  The control unit is a chip microcomputer or the like. The control unit has a memory in which a medicine spraying program is recorded. By processing the medicine spraying program by the control unit, the driving unit 200 is driven every predetermined period.

  Hereinafter, the operation of each component of the medicine spraying apparatus when the control unit drives the drive unit 200 will be described. When the control unit drives the driving unit 200, the first and second rotating shafts 210 and 220 rotate in the rotation direction D4. With the rotation of the first rotating shaft 210, the air blowing unit 100 rotates in the rotation direction D4, and thereby the wind is sent from the air blowing unit 100 in the air blowing direction D1. The wind passes through the case body 610 and is discharged out of the case body 610 through the first and second gaps S1 and S2 and the third and fourth gaps.

  On the other hand, with the rotation of the second rotation shaft 220, the worm gear 410 of the motion transmission unit 400 rotates in the rotation direction D4. Then, the worm wheel 420 and the gear 430 rotate in the blowing direction D1. As the gear 430 rotates, the first end 441 of the link rod 440 turns around the center of the gear 430 and the second end 442 of the link rod 440 and the second end 452 of the swing member 450 swing. Swings in direction D2. As a result, the first end 451 of the swing member 450 and the medicine container 300 swing in the swing direction D2 with the shaft support 453 as a fulcrum in the lee of the blower 100. In this way, the rotation of the second rotating shaft 220 is decelerated and converted to the first end 451 of the swinging member 450 and transmitted to the medicine container 300.

  As the drug container 300 swings, the wind discharged from the first and second gaps S1 and S2 is pressed by the inclined portions 312 and 322 of the drug container 300, and changes its direction from the blowing direction D1 to the conversion direction D3. The direction of the wind discharged from the third and fourth gaps changes from the blowing direction D1 to the obliquely downward direction along the inclined portions 332 and 342. At the same time, as the drug container 300 swings, the drug placed in the drug container 300 comes into contact with air through the through-hole 350 and diffuses. This medicine is sprayed on the wind passing through the first, second, third and fourth gaps.

  In the case of the medicine spraying device as described above, the medicine container 300 swings in the swinging direction D2 leeward of the air blowing unit 100, so that the medicine diffused from the medicine container 300 follows the wind generated in the air blowing part 100. Sprayed. Moreover, since the wind generated in the air blowing unit 100 is discharged out of the case 600 through the first, second, third, and fourth gaps of the case 600, the wind passes through the vicinity of the medicine container 300. For this reason, the medicine diffused from the medicine container 300 is easily sprayed on the wind. Therefore, the spraying efficiency of the medicine of the medicine spraying device can be improved.

  In addition, when the air blowing unit and the medicine container are arranged vertically (in the vertical direction), the direction of the wind generated from the air blowing unit is downward, so that the medicine spraying efficiency is reduced. However, in the medicine spraying device, the inclined portions 312 and 322 of the medicine container 300 can change the direction of the wind generated in the air blowing section 100 from the blowing direction D1 to the conversion direction D3 by the swinging of the medicine container 300. Even if the air blowing unit 100 and the medicine container 300 are arranged vertically (in the vertical direction), the medicine spraying efficiency of the medicine spraying apparatus can be improved. In addition, since the blower 100 and the medicine container 300 are arranged vertically (in the vertical direction), the horizontal projection area of the medicine spraying device can be reduced.

  Furthermore, since the medicine container 300 is configured such that the medicine container 300 swings in the lee of the air blowing unit 100, the medicine container 300 can make it difficult to block the wind generated by the air blowing unit 100. Therefore, it is possible to enlarge the external shape of the medicine 300. Alternatively, as described above, since the drug spraying efficiency of the drug spraying device is improved, the outer shape of the drug container 300 can be reduced in size. That is, the outer shape of the medicine container 300 can be appropriately sized in consideration of the spraying efficiency of the medicine and the hindrance to the wind generated in the blowing unit 100 of the medicine container 300.

  Moreover, since the said chemical | medical agent spraying apparatus is the structure to which the chemical | medical agent container 300 rock | fluctuates, it can give a visual healing effect with respect to a viewer.

  The above-described medicine spraying device is not limited to the above-described embodiment, and can be arbitrarily changed in design within the scope of the claims. Details will be described below.

  In the above embodiment, the air blowing unit 100 is a rotary fan. However, the design of the air blowing unit can be arbitrarily changed as long as it is possible to send wind in a predetermined air blowing direction. For example, the air blowing unit can be a swinging fan such as a fan.

  In the above embodiment, the driving unit 200 is an electric motor having the first and second rotating shafts 210 and 220. However, the design of the drive unit can be arbitrarily changed as long as it has a first drive unit that can drive the blower unit and a second drive unit that can swing or rotate the drug container. is there.
