[0005] Patent Document 1: Japanese Patent Publication No. 2020-51729 Summary of the Invention

[0006] -The technical problem the invention aims to solve-

[0007] To stably transport the vortex ring over a distance, a larger vortex ring is required, which necessitates increasing the amount of air ejected by the ejection mechanism. In the vortex ring generating device of Patent Document 1, to increase the amount of air ejected by the ejection mechanism, a vibrating plate installed in the ejection mechanism needs to be enlarged, thus resulting in an overall enlargement of the vortex ring generating device.

[0008] The purpose of this disclosure is to suppress the scaling up of vortex ring generating devices.

[0009] - Technical solutions for solving technical problems -

[0010] The first aspect of this disclosure pertains to a vortex ring generating apparatus.

[0011] The vortex generating device 10 releases a vortex-shaped airflow from the release port 55.

[0012] The vortex ring generating device includes multiple air chamber units A, and each of the multiple air chamber units A has an air chamber S that communicates with the release port 55.

[0013] Each of the plurality of air chamber units A has a stationary component 11 and a moving component 12.

[0014] The stationary component 11 forms the air chamber S.

[0015] The movable component 12 moves in a manner that pushes air out of the air chamber S.

[0016] All the moving parts 12 of the aforementioned air chamber units A are connected to form a moving body M; on the other hand,

[0017] The vortex ring generating device further includes a drive unit 13 and a connecting path C. The drive unit 13 is connected to the end of the movable body M, and the drive unit 13 drives the movable body M.

[0018] The connecting path C connects the air chambers S of the plurality of air chamber units A.

[0019] In the first aspect, since the vortex ring generating device 10 includes a plurality of air chamber units A, each air chamber unit A having a movable part 12, it is able to release more air compared to the case where the vortex ring generating device 10 includes only one air chamber unit A.

[0020] Furthermore, in this aspect, all the moving parts 12 of the air chamber units A are connected to form a moving body M. This moving body M is driven by a drive unit 13 connected to its end. Air pushed out of the air chamber S of each air chamber unit A by the action of the drive unit 13 is released from the release port 55 to the outside of the vortex ring generating device 10 through the connecting passage C. In this way, the amount of air released from the release port 55 can be increased without increasing the size of the moving parts 12 of each air chamber unit A. As a result, it is possible to prevent the vortex ring generating device 10 from becoming too large.

[0021] The second aspect of this disclosure is, based on the first aspect,

[0022] Multiple air chamber units A are arranged in a row.

[0023] The third aspect of this disclosure is, based on the first aspect,

[0024] The drive unit 13 causes the movable body M to reciprocate; on the other hand...

[0026] In the third aspect, since multiple air chamber units A are arranged in a row along the direction of movement of the moving body M, it is possible to suppress the vortex ring generating device 10 from becoming too large in the direction perpendicular to the direction of movement of the moving body M.

[0027] The fourth aspect of this disclosure is based on any one of the first to third aspects.

[0028] The movable component 12 and the stationary component 11 together form the air chamber S.

[0029] The plurality of said air chamber units A are divided into one or more first air chamber units A1 and one second air chamber unit A2.

[0030] The release port 55 is formed on the stationary component 11 of the second air chamber unit A2.

[0031] The movable body M is formed by interconnecting the movable parts 12 of all the air chamber units A.

[0032] The connecting path C connects the air chamber S of the first air chamber unit A1 with the air chamber S of the second air chamber unit A2.

[0033] In the fourth aspect, the air chamber S of the first air chamber unit A1 is connected to the air chamber S of the second air chamber unit A2 via the connecting passage C. Air pushed out from the air chamber S of the first air chamber unit A1 flows into the air chamber S of the second air chamber unit A2 via the connecting passage C, and together with the air in the air chamber S of the second air chamber unit A2, is released from the release port 55 formed in the second air chamber unit A2 to the outside of the vortex ring generating device 10. This shortens the connecting passage C, thus reducing the flow resistance of the connecting passage C.

[0077] In the seventeenth aspect, the sealing part 35 is used to seal the cylindrical part 33 of the passive moving part 30 between the stationary part 11 of the other air chamber unit A, thereby preventing air from leaking out between the cylindrical part 33 and the stationary part 11, which is located next to the air chamber unit A on which the passive moving part 30 is provided.

[0078] The eighteenth aspect of this disclosure is based on any one of aspects fourteen through seventeen.

[0091] The second space I2 constitutes the air chamber S.

[0092] The wall surface 81 has a recess 84 that connects the first space I1 to the outside of the connecting path C.

[0093] In the twentieth aspect, since the first space I1 is connected to the outside of the connecting passage C through the recess 84 of the wall surface 81, when the air in the air chamber S is pushed out by the movable member 12, air from the outside of the connecting passage C is drawn into the first space I1. This prevents the pressure in the first space I1 from decreasing as the movable member 12 moves. As a result, the movable member 12 can move smoothly.

[0094] The twenty-first aspect of this disclosure is, based on the twentieth aspect,

[0095] The release port 55 is formed on the passage forming component 100.

[0148] The passive moving part 30 has a passive flat plate portion 31, an elastic support member 22, a cylindrical portion 33, and a connecting portion 36. The passive flat plate portion 31 corresponds to the flat plate portion of this disclosure. The passive flat plate portion 31 is a plate-shaped member formed in an annular shape. The passive flat plate portion 31 faces the air chamber S of the second air chamber unit A2.

[0149] The axis of the passive plate section 31 is approximately coincident with the axis of the direct-moving plate section 21. In other words, each passive plate section 31 and the direct-moving plate section 21 is arranged coaxially. The passive plate section 31 and the direct-moving plate section 21 are arranged approximately parallel to each other. The passive plate section 31 and the direct-moving plate section 21 are arranged in the front-rear direction. The outer diameter of the passive plate section 31 is approximately equal to the outer diameter of the direct-moving plate section 21. The passive plate section 31 is positioned closer to the front than the first stationary member 40.

[0150] The elastic support member 22 of the passive moving member 30 is the same as the elastic support member 22 of the linear moving member 20. The elastic support member 22 of the passive moving member 30 is provided on the entire circumference of the outer periphery of the passive plate portion 31. The passive plate portion 31 and the elastic support member 22 are arranged to close the rearward open surface of the second stationary member 50. In other words, the passive plate portion 31 is connected to the second stationary member 50 via the elastic support member 22.

[0151] A through hole 32 is formed in the center of the passive flat plate portion 31. In other words, a through hole 32 is formed on the passive moving member 30. The through hole 32 is circular. The axis of the through hole 32 is approximately coincident with the axis of the passive flat plate portion 31. A cylindrical portion 33 is formed at the through hole 32 of the passive flat plate portion 31. In other words, the cylindrical portion 33 penetrates the flat plate portion 31.

[0152] The cylindrical portion 33 is a cylindrical section. The axis of the cylindrical portion 33 is approximately coincident with the axis of the passive plate portion 31. The cylindrical portion 33 extends rearward from the passive plate portion 31. The cylindrical portion 33 is arranged to be embedded inside the protrusion 43 of the first stationary member 40. One end (front end) of the cylindrical portion 33 is located closer to the front than the passive plate portion 31. The other end (rear end) of the cylindrical portion 33 is located closer to the rear than the communicating opening 44 of the first stationary member 40.

[0153] One end (front end) of the cylindrical portion 33 opens into the air chamber S of the second air chamber unit A2. The other end (rear end) of the cylindrical portion 33 opens into the air chamber S of the first air chamber unit A1. The cylindrical portion 33 connects the air chamber S of the second air chamber unit A2 with the air chamber S of the first air chamber unit A1. The inner diameter of the cylindrical portion 33 is larger than the diameter of the release port 55.

[0154] like Figure 2 As shown, a sealing recess 34 is formed between the cylindrical portion 33 and the passive flat plate portion 31. The sealing recess 34 is formed in an annular shape. The sealing recess 34 is recessed on the side of the first stationary member 40. The axis of the sealing recess 34 is substantially coincident with the axis of the cylindrical portion 33. The protrusion 43 of the first stationary member 40 is embedded in the sealing recess 34. The sealing recess 34 does not contact the protrusion 43. Therefore, the passive moving member 30 can move in the front-rear direction without being constrained by the first stationary member 40.

[0155] In this embodiment, a sealing portion 35 is formed by the sealing recess 34 of the passively moving member 30 and the protrusion 43 of the first stationary member 40. This sealing portion 35 is a labyrinth seal formed by allowing the protrusion 43 of the first stationary member 40 to enter the sealing recess 34 of the passively moving member 30. This sealing portion 35 is used to suppress air leakage between the cylindrical portion 33 of the passively moving member 30 and the first stationary member 40.

[0156] like Figure 2As shown by the dashed arrow, a portion of the air pushed out from the air chamber S of the first air chamber unit A1 flows into the narrow gap formed between the inner circumferential surface of the protrusion 43 and the outer circumferential surface of the cylindrical portion 33. The air entering this narrow gap is deflected back along the protruding end of the protrusion 43 and then flows further into the narrow gap extending along the outer circumferential surface of the protrusion 43. In this way, the air flowing into the gap formed between the inner circumferential surface of the protrusion 43 and the outer circumferential surface of the cylindrical portion 33 travels a relatively long distance in a very narrow gap. Therefore, the flow rate of air leaking through this gap is suppressed to a very low level.

[0157] The connecting portion 36 is an arc-shaped plate extending rearward from the other end (rear end) of the cylindrical portion 33. In this embodiment, four connecting portions 36 are formed. Each connecting portion 36 is arranged at equal intervals around the cylindrical portion 33 in the circumferential direction. Each connecting portion 36 opens towards the air chamber S of the first air chamber unit A1.

[0158] The rear end of each connecting portion 36 is bent radially inward. The outer side of the bent portion of each connecting portion 36 engages with the linearly moving plate portion 21. In other words, the connecting portion 36 connects the cylindrical portion 33 of the passively moving member 30 to the linearly moving member 20 of the first air chamber unit A1. In this way, the linearly moving member 20 and the passively moving member 30 are connected via the connecting portion 36, thereby forming a moving body M.

[0159] (Air chamber, connecting passage, air passage)

[0160] In the first air chamber unit A1, the space enclosed by the first main body part 41 and the first front plate part 42 of the first stationary member 40, and the linear plate part 21 and the elastic support member 22 of the linear moving member 20 is called the air chamber S.

[0161] In the second air chamber unit A2, the space enclosed by the second main body portion 51 and the second front plate portion 52 of the second stationary member 50, and the passive plate portion 31 and the elastic support member 22 of the passive moving member 30, becomes the air chamber S.

[0162] The vortex ring generating device 10 includes a connecting path C. The connecting path C connects the air chambers S of a plurality of air chamber units A. In this embodiment, the air chamber S of the first air chamber unit A1 and the air chamber S of the second air chamber unit A2 are connected via a cylindrical portion 33 of the passive moving member 30. The cylindrical portion 33 forms the connecting path C. In other words, the connecting path C connects the air chamber S of the first air chamber unit A1 and the air chamber S of the second air chamber unit A2. The connecting path C passes through the passive flat plate portion 31 of the passive moving member 30.

[0163] Inside the nozzle component 54, an air passage P extends from the rear end to the release port 55 at the front end. The air chamber S of the first air chamber unit A1 communicates with the release port 55 via the cylindrical portion 33, the air chamber S of the second air chamber unit A2, and the air passage P. The air chamber S of the second air chamber unit A2 communicates with the release port 55 via the air passage P. In other words, the air chamber S of each air chamber unit A is communicated with the release port 55.

[0164] <Drive Department>

[0165] The drive unit 13 is connected to the rear end of the movable body M. In this embodiment, the drive unit 13 is arranged behind the linearly moving member 20 located inside the first air chamber unit A1. The drive unit 13 is connected to the linearly moving plate portion 21 of the linearly moving member 20. The drive unit 13 is cylindrical. The drive unit 13 includes a magnet and a coil, and drives the movable body M using electromagnetic force; however, this is not shown in the figure. The axis of the main body portion 13a is approximately coincident with the axis of the linearly moving plate portion 21.

[0166] The drive unit 13 causes the movable body M to reciprocate in a straight line in the front-back direction. In other words, the drive unit 13 causes the movable body M to reciprocate in the arrangement direction (front-back direction) of the plurality of movable parts 12. Specifically, the drive unit 13 drives the movable body M such that all the movable parts 12 constituting the movable body M move simultaneously in the direction of pushing air out of the air chamber S corresponding to each movable part 12. The drive unit 13 causes the movable body M to vibrate between a reference position and a push-out position. In this way, the air in the air chamber S of each air chamber unit A is pushed forward.

[0167] -Operational Actions-

[0168] Reference Figure 3 The basic operation of the vortex ring generating device 10 will be explained.

[0169] When the vortex ring generating device 10 is in operation, the drive unit 13 causes the moving body M to reciprocate in the front-to-back direction. Specifically, the linearly moving component 20, which is directly connected to the drive unit 13, is driven by the drive unit 13. Furthermore, the passively moving component 30, which is connected to the linearly moving component 20, is driven as a unit along with the linearly moving component 20.

[0170] When the linear moving plate portion 21 of the linear moving part 20 moves forward due to the drive portion 13, Figure 3(As shown in position B2), the volume of the air chamber S of the first air chamber unit A1 decreases. When the volume of the air chamber S of the first air chamber unit A1 decreases, an air volume equal to the decrease in volume is pushed out of the air chamber S. The air pushed out of the air chamber S flows into the air passage P through the connecting passage C formed in the cylindrical portion 33 of the passive moving member 30 and the air chamber S of the second air chamber unit A2.

[0171] When the direct-acting movable part 20 moves forward, the passive plate part 31 of the passive movable part 30 also moves forward. Figure 3 (as shown in position B2). This reduces the volume of air chamber S in the second air chamber unit A2. When the volume of air chamber S in the second air chamber unit A2 decreases, an amount of air equal to the reduction in volume is expelled from air chamber S. The air expelled from air chamber S flows into air passage P and merges with the air flowing in from air chamber S in the first air chamber unit A1. The merged air flows towards the release port 55 in air passage P.

[0172] Air is released from the outlet 55 at a relatively high velocity, while the air around the outlet 55 is still. Therefore, at the discontinuity between these two air masses, shear forces act on the air, generating vortices near the outer periphery of the outlet 55. These vortices create a ring-shaped airflow that propagates from the outlet 55. Figure 1 and Figure 3 The vortex ring R is represented by a double-dotted line.

[0173] The drive unit 13 performs a reciprocating motion once at predetermined time intervals. Specifically, in the vortex ring generating apparatus 10 of this embodiment, after generating one vortex ring R, a predetermined time interval is maintained before generating the next vortex ring R. In this embodiment, the predetermined time interval is 5 to 10 seconds. Alternatively, the drive unit 13 may perform multiple reciprocating vibrations, then a predetermined time interval is maintained before performing multiple reciprocating vibrations again. For example, the following operation may be repeated: after generating three vortex rings R consecutively at 0.3-second intervals, a predetermined time interval is maintained before generating the next three vortex rings R consecutively.

[0174] -Motion of moving parts-

[0175] When the vortex ring generating device 10 operates, the moving body M reciprocates between the reference position and the extended position. When the drive unit 13 stops, the moving body M is at the reference position. At the reference position ( Figure 3 (as shown in position B1), the displacement of the direct-acting moving part 20 and the passive moving part 30 is zero. On the other hand, when the moving body M is in the extended position (… Figure 3When in position B2, the direct-acting movable member 20 and the passive-acting movable member 30 move to the front. In other words, the direct-acting movable member 20 and the passive-acting movable member 30 are in a forward-bulging state.

[0176] The distance from the reference position to the ejection position is the stroke L of the drive unit 13. Here, when the moving body M moves from the reference position to the ejection position once, the volume V1 of air ejected from the air chamber S of the first air chamber unit A1 is the value obtained by multiplying the front surface area S1 of the direct-moving plate part 21 by the stroke L (V1 = S1 × L). In addition, the volume V2 of air ejected from the air chamber S of the second air chamber unit A2 is the value obtained by multiplying the front surface area S2 of the passive plate part 31 by the stroke L (V2 = S2 × L). Furthermore, the volume V of air released from the vortex ring generating device 10 each time the moving body M moves is the sum of V1 and V2 (V = V1 + V2).

[0177] In this way, by connecting multiple air chamber units A, the amount of air released from the vortex ring generating device 10 can be increased compared to the case where only one air chamber unit is provided in the vortex ring generating device 10. In addition, by arranging multiple air chamber units A in a row along the moving direction of the moving body M, it is possible to prevent the vortex ring generating device 10 from becoming larger radially outward.

[0178] -Features of the first embodiment (1)-

[0179] In the vortex ring generating device 10 of this embodiment, all the movable parts 12 of the air chamber units A are connected together to form a movable body M. Furthermore, the vortex ring generating device 10 includes a drive unit 13 and a connecting passage C. The drive unit 13 is connected to the end of the movable body M and drives the movable body M. The connecting passage C connects the air chambers S of the multiple air chamber units A.

[0180] In the vortex ring generating apparatus 10 of this embodiment, since each of the plurality of air chamber units A has an air chamber S formed therein, and each air chamber unit A has a movable member 12 for pushing air out of the air chamber S, more air can be released compared to the case where air is pushed out from the air chamber S of one air chamber unit A.

[0181] Furthermore, in the vortex ring generating apparatus 10 of this embodiment, the movable parts 12 of all the air chamber units A are connected together to form a movable body M. This movable body M is driven by a drive unit 13 connected to an end of the movable body M. Air pushed out from the air chamber S of each air chamber unit A by the operation of the drive unit 13 is released to the outside of the vortex ring generating apparatus 10 through the connecting passage C and the release port 55. In this way, the amount of air released from the release port 55 can be increased without increasing the size of the movable parts 12 of each air chamber unit A. As a result, it is possible to prevent the vortex ring generating apparatus 10 from becoming too large.

[0182] -Features of the first embodiment (2)-

[0183] In this embodiment, multiple air chamber units A are arranged in a row.

[0184] -Features of the first embodiment (3)-

[0185] In the vortex ring generating device 10 of this embodiment, the drive unit 13 causes the moving body M to reciprocate, while multiple air chamber units A are arranged in a row along the moving direction of the moving body M.

[0186] Since multiple air chamber units A are arranged in a row along the direction of movement of the moving body M, it is possible to suppress the vortex ring generating device 10 from becoming too large in the direction perpendicular to the direction of movement of the moving body M.

[0187] -Features of the first embodiment (4)-

[0188] In the vortex ring generating device 10 of this embodiment, all the moving parts 12 of the air chamber units A are interconnected to form a moving body M. Furthermore, the vortex ring generating device 10 includes a drive unit 13 and a connecting path C. The drive unit 13 drives the moving body M, and the connecting path C connects the air chamber S of the first air chamber unit A1 with the air chamber S of the second air chamber unit A2.

[0189] The air chamber S of the first air chamber unit A1 is connected to the air chamber S of the second air chamber unit A2 via the connecting passage C. Air pushed out from the air chamber S of the first air chamber unit A1 flows into the air chamber S of the second air chamber unit A2 via the connecting passage C, and together with the air in the air chamber S of the second air chamber unit A2, is released from the release port 55 formed in the second air chamber unit A2 to the outside of the vortex ring generating device 10. This shortens the connecting passage C, thus reducing the flow resistance of the connecting passage C.

[0190] -Features of the first embodiment (5)-

[0191] In the vortex ring generating apparatus 10 of this embodiment, one of the multiple moving parts 12 constituting the moving body M is a direct-acting moving part 20 that is directly connected to the drive unit 13, and the moving parts 12 constituting the moving body M other than the direct-acting moving part 20 are passive moving parts 30 that are driven by the drive unit 13 via the direct-acting moving part 20.

[0192] Since the passive moving part 30 is driven by the drive unit 13 via the direct moving part 20, the drive unit 13 can drive multiple moving parts 12.

[0193] -Features of the first embodiment (6)-

[0194] In this embodiment, the movable part 12 of each air chamber unit A has a flat plate portion 21, 31 facing the air chamber S.

[0195] Since the plate sections 21 and 31 face the air chamber S, the air in the air chamber S is pushed out when the plate sections 21 and 31 move.

[0196] -Features of the first embodiment (7)-

[0197] In this embodiment, the flat plate portions 21 and 31 of each movable component 12 are formed in a circular shape and arranged coaxially with each other.

[0198] Since the plate portions 21 and 31 are circular, a uniform airflow can be formed in the circumference of the plate portions 21 and 31. In addition, since the plate portions 21 and 31 are arranged coaxially with each other, the air pushed out by the plate portions 21 and 31 flows in the same direction.

[0199] -Features of the first embodiment (8)-

[0200] In this embodiment, the drive unit 13 causes the movable body M to reciprocate in the arrangement direction of the plurality of movable parts 12 constituting the movable body M.

[0201] As the drive unit 13 causes the movable body M to reciprocate in the arrangement direction of the plurality of movable parts 12, the air in the air chamber S of each air chamber unit A is pushed out along the arrangement direction of the plurality of movable parts 12.

[0202] -Features of the first embodiment (9)-

[0203] In this embodiment, the connecting path C passes through the flat plate portion 21, 31 of at least one movable member 12.

[0204] Since the connecting path C passes through the flat plate portion 21, 31 of at least one movable component 12, it is not necessary to use a new component to form the connecting path C.

[0205] -Features of the first embodiment (10)-

[0206] One of the multiple movable parts 12 constituting the movable body M in this embodiment is a linearly moving part 20 that is directly connected to the drive unit 13. In addition, the movable parts 12 constituting the movable body M in this embodiment, other than the linearly moving part 20, are passively moving parts 30 that are driven by the drive unit 13 via the linearly moving part 20. Furthermore, a through hole 32 constituting a communication path C is formed in the passively moving part 30.

[0207] Since the passive moving part 30 is driven by the drive unit 13 via the direct moving part 20, the drive unit 13 can drive multiple moving parts 12. In addition, since the passive moving part 30 has a through hole 32 forming the communication path C, it is not necessary to form the communication path C with a new part.

[0208] -Features of the first embodiment (11)-

[0209] In this embodiment, the through hole 32 is formed in the center of the flat plate portion 21, 31 of the passive moving member 30.

[0210] Since the through hole 32 is formed in the center of the flat plate portions 21 and 31 of the passive moving member 30, the air pushed out by the other flat plate portions 21 and 31 passes through the center of the flat plate portions 21 and 31.

[0211] -Features of the first embodiment (12)-

[0212] In this embodiment, the through hole 32 is formed as a circle.

[0213] Since the through hole 32 is formed in a circular shape, a uniform airflow can be formed in the circumference of the through hole 32.

[0214] -Features of the first embodiment (13)-

[0215] At least one movable component 12 in this embodiment has: a flat plate portion 21, 31 facing the air chamber S; and a cylindrical portion 33 that passes through the flat plate portion 21, 31 to form a connecting passage C.

[0216] At least one movable component 12 has a flat plate portion 21, 31 and a cylindrical portion 33. When the flat plate portions 21, 31 move, air in the air chamber S facing the flat plate portions 21, 31 is pushed out. In addition, the cylindrical portion 33 passing through the flat plate portions 21, 31 forms at least a portion of the communication path C.

[0217] -Features of the first embodiment (14)-

[0218] In this embodiment, both the direct-acting movable member 20 and the passive-acting movable member 30 have flat plate portions 21 and 31 facing the air chamber S. Among the direct-acting movable member 20 and the passive-acting movable member 30, only the passive-acting movable member 30 also has a cylindrical portion 33, which penetrates the flat plate portions 21 and 31 to form a connecting passage C.

[0219] Both the direct-acting member 20 and the passive-acting member 30 have flat plate portions 21 and 31, which push air out of the air chamber S. In addition, the air pushed out by the flat plate portion 21 of the direct-acting member 20 passes through the cylindrical portion 33 of the passive-acting member 30.

[0220] -Features of the first embodiment (15)-

[0221] In this embodiment, the cylindrical portion 33 of the passively moving member 30 connects the air chamber S of the air chamber unit A on which the passively moving member 30 is provided with the air chamber S of other air chamber units A, which are located next to the air chamber unit A on which the passively moving member 30 is provided.

[0222] Air pushed out from the air chamber S of other air chamber units A flows into the air chamber S of air chamber unit A, which is provided with a passively moving member 30 having the cylindrical portion 33, through the cylindrical portion 33. The other air chamber units A are located next to the air chamber unit A, which is provided with the passively moving member 30 having the cylindrical portion 33.

[0223] -Features of the first embodiment (16)-

[0224] The stationary component 11 of another air chamber unit A located next to the air chamber unit A where the passive moving component 30 of this embodiment is provided has a communication opening 44, which allows the air chamber S of the other air chamber unit A to communicate with the cylindrical portion 33 of the moving component 12.

[0225] -Features of the first embodiment (17)-

[0226] The vortex ring generating device of this embodiment includes a sealing part 35, which seals the cylindrical part 33 of the passive moving part 30 of this embodiment between the other stationary part 11 of the other air chamber unit A, which is located next to the air chamber unit A on which the passive moving part 30 is provided.

[0227] By using the sealing part 35, the cylindrical part 33 of the passive moving part 30 is sealed between the stationary part 11 of the other air chamber unit A, thereby preventing air from leaking out between the cylindrical part 33 and the stationary part 11, wherein the other air chamber unit A is located next to the air chamber unit A on which the passive moving part 30 is provided.

[0228] -Features of the first embodiment (18)-

[0229] The passive moving part 30 of this embodiment has a connecting part 36, which connects the cylindrical part 33 of the passive moving part 30 to the direct moving part 20 or the passive moving part 30 of other air chamber unit A, wherein the other air chamber unit A is located next to the air chamber unit A that is provided with the passive moving part 30 having the connecting part 36.

[0230] Since the passive moving part 30 has a connecting part 36, the driving force of the driving part 13 is transmitted from the direct moving part 20 or the passive moving part 30 of the other air chamber unit A to the passive moving part 30 having a cylindrical part 33 via the connecting part 36. The other air chamber unit A is located next to the air chamber unit A on which the passive moving part 30 is provided, and the passive moving part 30 has a cylindrical part 33.

[0231] Second Implementation Method

[0232] The second embodiment will be described. The vortex ring generating device 10 of this embodiment is obtained by changing the number of gas chamber units A based on the vortex ring generating device 10 of the first embodiment. Here, the differences between the vortex ring generating device 10 of this embodiment and the vortex ring generating device 10 of the first embodiment will be explained.

[0233] like Figure 4 As shown, the vortex ring generating device 10 of this embodiment includes five gas chamber units A. It should be noted that the number of gas chamber units A shown here is only an example.

[0234] <Air cell unit>

[0235] In the vortex ring generating apparatus 10 of this embodiment, the five air chamber units A are divided into four first air chamber units A1 and one second air chamber unit A2. One first air chamber unit A1 is arranged in front of the drive unit 13. The first air chamber units A1 are arranged adjacent to each other. The second air chamber unit A2 is arranged in front of the foremost first air chamber unit A1. Similar to the first embodiment, each first air chamber unit A1 includes a first stationary component 40, and each second air chamber unit A2 includes a second stationary component 50.

[0236] In the vortex ring generating device 10 of this embodiment, similar to the first embodiment, each air chamber unit A has a movable component 12. The five movable components 12 are interconnected to form a movable body M.

[0237] The five moving parts 12 constituting the moving body M are divided into one direct-acting moving part 20 and four passive moving parts 30. In the vortex ring generating device 10 of this embodiment, the moving part 12 of the rearmost first air chamber unit A1 among the four first air chamber units A1 is the direct-acting moving part 20, and the moving parts 12 respectively provided in the other three first air chamber units A1 and the second air chamber unit A2 are passive moving parts 30.

[0238] The last first air chamber unit A1 has a first stationary component 40, a drive unit support component 60, and a direct-moving component 20. The other three first air chamber units A1 each have a first stationary component 40 and a passively moving component 30. The second air chamber unit A2 has a second stationary component 50 and a passively moving component 30.

[0239] (First stationary component)

[0240] The first stationary component 40 includes a first main body portion 41, a first front plate portion 42, and a first rear plate portion 46. The first stationary component 40 of this embodiment differs from the first stationary component of the first embodiment in that it further includes the first rear plate portion 46 and does not include the protrusion or connecting portion. The first rear plate portion 46 corresponds to the connecting plate portion 62 of the drive unit support component 60 in the first embodiment. A communicating opening 44 is formed in the center of the first front plate portion 42.

[0241] (Second stationary component)

[0242] The second stationary component 50 includes a second main body portion 51, a second front plate portion 52, and a second rear plate portion 53. The second stationary component 50 of this embodiment differs from the second stationary component of the first embodiment in that it does not include a nozzle component. A release port 55 is formed in the center of the second front plate portion 52.

[0243] (Directly moving parts, passively moving parts)

[0244] The structure of the direct-acting movable member 20 is the same as that of the direct-acting movable member in the first embodiment described above. The passive movable member 30 includes a passive flat plate portion 31, a cylindrical portion 33, a closed flat plate portion 38, a first elastic support member 22a, a second elastic support member 22b, and a connecting portion 36. The structures of the passive flat plate portion 31 and the cylindrical portion 33 are the same as those in the first embodiment described above.

[0245] The closed plate portion 38 is a plate-shaped portion extending radially outward from the rear end of the cylindrical portion 33. The closed plate portion 38 is formed into a flat annular shape. The closed plate portion 38 is arranged such that it covers the open surface of the first front plate portion 42 of the air chamber unit A, which is arranged behind the air chamber unit A having the closed plate portion 38.

[0246] The first elastic support member 22a and the second elastic support member 22b are frame-shaped members made of elastic materials such as rubber, the same as the elastic support members in the first embodiment described above. The first elastic support member 22a is provided on the entire circumference of the outer peripheral edge of the passive plate portion 31. The first elastic support member 22a connects the passive plate portion 31 to the first rear plate portion 46 of the air chamber unit A having the passive plate portion 31.

[0247] The second elastic support member 22b is disposed on the entire circumference of the outer periphery of the closed plate portion 38. The second elastic support member 22b connects the closed plate portion 38 to the first front plate portion 42 of the air chamber unit A described below, wherein the air chamber unit A is located behind the air chamber unit A having the closed plate portion 38. The second elastic support member 22b constitutes a sealing portion 35, which seals between the passively moving member 30 having the second elastic support member 22b and the stationary member 11 of the air chamber unit A described below, wherein the air chamber unit A is located behind the air chamber unit A having the second elastic support member 22b.

[0248] The connecting portion 36 connects the cylindrical portion 33 of the passive moving member 30 to the direct moving member 20 or the passive moving member 30 of other air chamber units A, which are located behind the air chamber unit A having the passive moving member 30 with the cylindrical portion 33. The connecting portion 36 is a rod-shaped member extending rearward from the rear surface of the passive flat plate portion 31. In this embodiment, four connecting portions 36 are formed.

[0249] (Connecting path)

[0250] In this embodiment, the connecting path C is formed by four cylindrical portions 33 arranged in a straight line. In other words, each of the four cylindrical portions 33 forms a part of the connecting path C.

[0251] In the vortex ring generating apparatus 10 of this embodiment, the air chamber S of each first air chamber unit A1 is connected to the air chamber S of the second air chamber unit A2 via the connecting passage C. Furthermore, when the drive unit 13 moves the movable body M, air pushed out from the air chamber S of each first air chamber unit A1 flows into the air chamber S of the second air chamber unit A2 through the connecting passage C, and is released from the release port 55 together with air pushed out by the movable member 12 of the second air chamber unit A2. As a result, a vortex ring R is formed.

[0252] Third Implementation Method

[0253] The third embodiment will be described. Here, the differences between the vortex ring generating device 10 of this embodiment and the vortex ring generating device 10 of the second embodiment will be explained.

[0254] like Figure 5 As shown, the vortex ring generating device 10 of this embodiment includes four gas chamber units A and three drive units 13.

[0255] <Air cell unit>

[0256] In the vortex ring generating apparatus 10 of this embodiment, the four gas chamber units A are divided into three first gas chamber units A1 and one second gas chamber unit A2. Each first gas chamber unit A1 is arranged around a second gas chamber unit A2.

[0257] Similar to the second embodiment, each first air chamber unit A1 includes a stationary component 11 and a movable component 12. The stationary component 11 of each first air chamber unit A1 is a first stationary component 40. A drive unit support component 60 is arranged on the first rear plate portion 46 side of each first stationary component 40. Each drive unit support component 60 is fixed to each first stationary component 40. A drive unit 13 is installed on each first air chamber unit A1. In each first air chamber unit A1, the movable component 12 is connected to the drive unit 13. The movable component 12 of each first air chamber unit is a linearly moving component 20.

[0258] The second air chamber unit A2 includes a stationary component 11 and three movable components 12. The stationary component 11 of the second air chamber unit A2 is a second stationary component 50. In this embodiment, the second stationary component 50 is formed into a hollow cubic shape. The second stationary component 50 has a release port 55 on one of its four sides, and a movable component 12 is provided on each of the other three sides. The three movable components 12 correspond to a first air chamber unit A1. Each movable component 12 is a passive movable component 30 connected to the direct-moving movable component 20 of the corresponding first air chamber unit A1.

[0259] (Active entity)

[0260] A linearly moving part 20 and a passively moving part 30, which are interconnected, constitute a moving body M. In the vortex ring generating device 10 of this embodiment, three moving bodies M are formed, and each moving body M is connected to a drive unit 13. Each drive unit 13 causes its corresponding moving body M to reciprocate.

[0261] (Connecting path)

[0262] In the vortex ring generating apparatus 10 of this embodiment, each of the three moving bodies M forms a connecting path C. Therefore, in the vortex ring generating apparatus 10 of this embodiment, three connecting paths C are formed. In each moving body M, the connecting path C is formed by the cylindrical portion 33 of the passive moving member 30. The connecting path C formed by each moving body M connects the air chamber S of the first air chamber unit A1, on which the moving body M is provided, with the air chamber S of the second air chamber unit A2.

[0263] When each drive unit 13 moves a corresponding movable body M, the air pushed out of the air chamber S of each first air chamber unit A1 flows into the air chamber S of the second air chamber unit A2 through each connecting passage C, and is released from the release port 55 together with the air pushed in by the three passive moving parts 30 of the second air chamber unit A2. As a result, a vortex ring R is formed.

[0264] Fourth Implementation Method

[0265] The fourth embodiment will be described. The vortex ring generating apparatus 10 of this embodiment is obtained by modifying the structure of the gas chamber unit A and the position of the connecting path C based on the vortex ring generating apparatus 10 of the first embodiment. Here, the differences between the vortex ring generating apparatus 10 of this embodiment and the vortex ring generating apparatus 10 of the first embodiment will be explained.

[0266] like Figures 6-10 As shown, the vortex ring generating apparatus 10 of this embodiment includes a plurality of air chamber units A, a drive unit 13, and a passage forming member 100 forming a connecting path C. In this embodiment, the vortex ring generating apparatus 10 includes four air chamber units A. It should be noted that the number of air chamber units A shown here is only an example.

[0267] <Air cell unit>

[0268] In this embodiment, the four air chamber units A are all air chamber units with the same structure. Each air chamber unit A is arranged in a straight line in the front-to-back direction. Each air chamber unit A has a stationary part 11 and a moving part 12.

[0269] (Stationary component)

[0270] like Figures 7-9 As shown, the stationary component 11 has a cylindrical portion 71 and a wall portion 81. The cylindrical portion 71 is formed on the first component 70. The wall portion 81 is formed on the second component 80. The first component 70 is arranged on the front side of the second component 80. In the vortex ring generating apparatus 10 of this embodiment, the first component 70 and the second component 80 are arranged alternately in the front-rear direction.

[0271] The first component 70 has a cylindrical portion 71 and four cylindrical side flange portions 72. The cylindrical portion 71 is formed in the shape of a short cylinder. The cylindrical portion 71 is arranged with its axis facing in the front-rear direction. An internal space I is formed inside the cylindrical portion 71.

[0272] Each cylindrical side flange 72 is formed in the shape of a plate. Each cylindrical side flange 72 protrudes laterally from the outer periphery of the cylindrical portion 71. Each cylindrical side flange 72 is arranged such that its plane is approximately parallel to the ground. Two cylindrical side flanges 72 are provided on each side of the cylindrical portion 71, with the cylindrical portion 71 as the center. The two cylindrical side flanges 72 on the right side are arranged vertically and vertically at a predetermined interval in the circumferential direction. The two cylindrical side flanges 72 on the left side are arranged in the same way as the cylindrical side flanges 72 on the right side.

[0273] The second component 80 has a wall surface portion 81 and four wall side flange portions 82. The wall surface portion 81 is formed in the shape of a circular plate. The wall surface portion 81 is arranged to close one end (rear end) of the cylindrical portion 71 of the first component 70. The center of the wall surface portion 81 is approximately coincident with the axis of the cylindrical portion 71. A circular stationary side hole 83 is formed in the center of the wall surface portion 81. The stationary side hole 83 extends through the wall surface portion 81 along the thickness direction. The shaft portion 96 of the movable body M, described later, is inserted into the stationary side hole 83.

[0274] Each wall-side flange 82 is formed in the shape of a plate. Each wall-side flange 82 protrudes laterally from the outer periphery of the wall surface 81. Each wall-side flange 82 is arranged such that its plane is approximately parallel to the ground. Two wall-side flanges 82 are provided on each side of the wall surface 81 as the center. The two wall-side flanges 82 on the right side are arranged vertically and vertically at a predetermined interval in the circumferential direction. The two wall-side flanges 82 on the left side are arranged in the same way as the wall-side flanges 82 on the right side. Each wall-side flange 82 is set at the same height as the corresponding cylindrical flange 72.

[0275] All stationary components 11 have cylindrical portions 71 of equal diameter. All cylindrical portions 71 are arranged such that their axes substantially coincide. All stationary components 11 have wall portions 81 of equal diameter. All wall portions 81 are arranged such that their centers substantially coincide with the axis of the cylindrical portion 71. A space is formed between the cylindrical portion 71 of each stationary component 11 and the wall portions 81 of other chamber units A located adjacent to the chamber unit A on which the stationary component 11 is located. In other words, the cylindrical portion 71 of each stationary component 11 does not contact the wall portions 81 of other chamber units A located adjacent to the chamber unit A on which the stationary component 11 is located.

[0276] (Moving parts, moving bodies)

[0277] like Figure 8As shown, the movable component 12 has a movable planar portion 90. The movable planar portion 90 corresponds to the first planar portion of this disclosure. The movable planar portion 90 is a circular planar portion. The movable planar portion 90 is arranged in the internal space I of the cylindrical portion 71. Specifically, the movable planar portion 90 is arranged to span the internal space I of the cylindrical portion 71.

[0278] The movable plane portion 90 divides the internal space I of the cylindrical portion 71 into a first space I1 located at one end (rear end) of the cylindrical portion 71 and a second space I2 located at the other end (front end) of the cylindrical portion 71. The first space I1 faces the wall surface 81 of the second component 80. The second space I2 constitutes the air chamber S. In other words, the front surface of the movable plane portion 90 faces the air chamber S. In the air chamber unit A of this embodiment, the space enclosed by the inner surface of the cylindrical portion 71 and the front surface of the movable plane portion 90 is called the air chamber S.

[0279] A circular movable side hole 91 is formed in the center of the movable plane portion 90. The movable side hole 91 penetrates the movable plane portion 90 along the thickness direction. The shaft portion 96 of the movable body M, described later, is inserted into the movable side hole 91.

[0280] The movable planar portion 90 is capable of moving in the front-to-back direction within the internal space I of the cylindrical portion 71. A tiny gap is formed between the outer periphery of the movable planar portion 90 of each air chamber unit A and the inner periphery of the cylindrical portion 71. This tiny gap is formed such that when the movable planar portion 90 moves forward and pushes out the air from the air chamber S, the air will not leak from the gap into the first space I1.

[0281] The movable planar portion 90 has a skeleton member 92 and a thin film 95 covering the surface of the skeleton member 92. The skeleton member 92 forms the outline of the movable planar portion 90 and holds the thin film 95. Figure 7 and Figure 10 As shown, the skeleton component 92 includes an outer frame 93 and a support frame 94.

[0282] The outer frame 93 is formed in a ring shape and has the outline of the movable plane portion 90. The support frame 94 is composed of multiple strip-shaped portions and ring-shaped portions. The multiple strip-shaped portions extend radially from the movable side hole 91 toward the outer frame 93, and the ring-shaped portions connect the strip-shaped portions to each other. The support frame 94 holds the membrane 95. The skeleton member 92 is formed by hollowing out a thin circular plate. The membrane 95 is formed as a thin film. The membrane 95 covers the entire surface of the skeleton member 92.

[0283] The movable body M of this embodiment has movable planar portions 90 and shaft portions 96 for all air chamber units A. The shaft portions 96 are inserted into all movable planar portions 90, and all movable planar portions 90 are fixed to the shaft portions 96. The movable body M of this embodiment is composed of four movable planar portions 90 and shaft portions 96. The shaft portion 96 is a rod-shaped component with a circular cross-section. A drive unit 13 is connected to the rear end of the shaft portion 96. The frontmost movable planar portion 90 is fixed to the front end of the shaft portion 96. The shaft portion 96 is fixed to each movable planar portion 90 via a planar fixing member 97 formed in a cylindrical shape. All movable planar portions 90 are fixed to the shaft portion 96 via the planar fixing member 97, thereby allowing all movable components 12 to move as a single unit.

[0284] The shaft portion 96 is inserted into the resting side hole 83 of each wall surface 81. The shaft portion 96 is supported by the beginning (foremost) and end (rearmost) wall surface 81 via the shaft portion support member 98. The shaft portion 96 is supported by the shaft portion support member 98 and is able to move in the front-rear direction. The shaft portion support member 98 is formed in a cylindrical shape. Each shaft portion support member 98 is arranged in the resting side hole 83 of the beginning and end wall surface 81. In other words, the shaft portion support member 98 is not arranged in the resting side hole 83 of the second and third wall surface 81 from the beginning.

[0285] A small gap is formed between the stationary side hole 83 of the wall surface 81 (where the shaft support member 98 is not located) and the shaft 96. This small gap is formed such that when the movable plane 90 moves forward and pushes air out of the air chamber S, air will not leak from the gap into the first space I1. Simultaneously, this small gap is formed such that when the movable plane 90 moves, the outer periphery of the shaft 96 does not contact the inner periphery of the stationary side hole 83 of the wall surface 81. Thus, the shaft 96 is supported by a portion of the wall surface 81 of the stationary member 11. Therefore, the shaft 96 can slide more smoothly when it moves in the front-rear direction.

[0286] <Connecting path and pathway forming components>

[0287] like Figure 6 and Figure 7 As shown, the vortex ring generating device 10 includes a passage forming component 100. The passage forming component 100 is a component for forming a connecting passage C. The passage forming component 100 has an upper cover component 101, a lower cover component 102, a front cover component 105, a right cover component 103, and a left cover component 104.

[0288] like Figure 8 and Figure 10As shown, the upper cover component 101 is arranged on the upper side of each air chamber unit A. The lower cover component 102 is arranged on the lower side of each air chamber unit A. The upper cover component 101 and the lower cover component 102 are plate-shaped components. The upper cover component 101 has a cover body 111, a cover side flange portion 112, and a rear closure portion 113.

[0289] The cover body 111 has an arc-shaped cross-section. Side flanges 112 extend laterally from both ends of the cover body 111. A rear closure 113 closes the rear end of the cover body 111. The side flanges 112 are fastened to the cylinder-side flange 72 and the wall-side flange 82. The rear closure 113 is located behind the wall surface 81 of the rearmost second component 80.

[0290] The lower cover component 102 is constructed in the same manner as the upper cover component 101. The cover body 111 of the upper cover component 101 is arranged to cover the upper part of the cylindrical portion 71. The cover body 111 of the lower cover component 102 is arranged to cover the lower part of the cylindrical portion 71. The cover side flange 112 of the lower cover component 102 is fixed to the base 14 provided below the lower cover component 102.

[0291] A front cover component 105 is disposed at the front end of the upper cover component 101 and the lower cover component 102. The front cover component 105 is formed in the shape of a circular plate. The front cover component 105 corresponds to the second planar portion of this disclosure. The front cover component 105 is disposed in front of the foremost air chamber unit A. A release port 55 is formed in the center of the front cover component 105. The release port 55 is a circular opening.

[0292] The right cover component 103 and the left cover component 104 are plate-shaped components. The right cover component 103 is arranged to the right of the front cover component 105. The right cover component 103 is arranged vertically between the upper cover component 101 and the lower cover component 102. The left cover component 104 is arranged to the left of the front cover component 105. The left cover component 104 is arranged vertically between the upper cover component 101 and the lower cover component 102.

[0293] The right cover component 103 has a side cover body 114 and a side flange portion 115. The side cover body 114 has an arc-shaped cross-section. The side flange portion 115 extends laterally from both the upper and lower ends of the side cover body 114. The side flange portion 115 is arranged such that its plane is approximately parallel to the ground. The upper side flange portion 115 is fastened to the cover flange portion 112 of the upper cover component 101. The lower side flange portion 115 is fastened to the cover flange portion 112 of the lower cover component 102. The left cover component 104 is constructed in the same manner as the right cover component 103.

[0294] The connecting path C is formed by the passage forming member 100. The air chambers S of each air chamber unit A are connected by the connecting path C. The connecting path C is connected to the release port 55. In other words, the air chambers S of each air chamber unit A are connected to the release port 55. In this embodiment, the connecting path C is formed on the outer side of the cylinder portion 71. Specifically, the connecting path C includes an upper passage C1, a lower passage C2, and a central passage C3.

[0295] An upper passage C1 is formed between the upper cover member 101 and the cylindrical portion 71 of each air chamber unit A. In other words, the upper passage C1 is formed on the upper side of the cylindrical portion 71. A lower passage C2 is formed between the lower cover member 102 and the cylindrical portion 71 of each air chamber unit A. In other words, the lower passage C2 is formed on the lower side of the cylindrical portion 71.

[0296] A central passage C3 is formed in the space enclosed by the upper cover component 101, the lower cover component 102, the right cover component 103, the left cover component 104, and the front cover component 105. The central passage C3 is formed in front of the foremost cylindrical section 71. The central passage C3 is formed between the upper passage C1 and the lower passage C2 and the release port 55. The upper passage C1 and the lower passage C2 connect the air chambers S of each air chamber unit A to each other. The central passage C3 connects the upper passage C1 and the lower passage C2 to the release port 55.

[0297] <Buffer component>

[0298] like Figure 8 As shown, the vortex ring generating device 10 includes a first buffer component 15 and four second buffer components 16. The first buffer component 15 and the second buffer components 16 are provided to suppress the sound generated when the components come into contact with each other as the moving body M moves.

[0299] Specifically, such as Figure 11 As shown, the first buffer member 15 is fixed to the surface of one end (rear side) of the rearmost wall surface 81 via the buffer fixing member 15a. The first buffer member 15 is arranged vertically with the stationary side hole 83 of the wall surface 81 as the center. The first buffer member 15 is formed into a rectangular thin plate shape. The buffer fixing member 15a is arranged to protrude rearward (towards the drive part 13) from the surface of one end (rear side) of the rearmost wall surface 81. The first buffer member 15 is fixed to the protruding end of the buffer fixing member 15a. By arranging the first buffer member 15 in this way, it is possible to suppress the sound generated when the moving body M moves from the reference position to the extension position due to the contact between the drive part 13 and the wall surface 81 closest to the drive part 13.

[0300] The second buffer member 16 is fixed to the center of the other end (front) side of each wall surface 81. The second buffer member 16 is formed in an approximately annular shape. The second buffer member 16 is arranged to surround the entire circumference of the stationary side hole 83 of the wall surface 81. By setting the second buffer member 16 in this way, when the movable body M moves from the push-out position to the reference position, the sound generated due to the contact between the wall surface 81 of each air chamber unit A and the movable plane portion 90 can be suppressed.

[0301] <Inhalation route>

[0302] like Figure 9 As shown, the vortex ring generating device 10 includes a suction passage F. The suction passage F is a passage for connecting the first space I1 of the cylindrical portion 71 to the outside of the connecting passage C. The suction passage F is formed in the internal space of the suction recess 84. In other words, the suction recess 84 connects the first space I1 to the outside of the connecting passage C. The suction recess 84 corresponds to the recess of this disclosure.

[0303] An intake recess 84 is formed on the wall surface 81 of each air chamber unit A. One intake recess 84 is formed on each of the left and right sides of the wall surface 81. The intake recesses 84 on the right and left sides are formed at the center of the vertical direction of the wall surface 81. Each intake recess 84 is recessed towards the rear. The bottom surface 84a of the intake recess 84 is a rectangle with the vertical direction as its longer side and the horizontal direction as its shorter side.

[0304] The second component 80 has two protrusions 85. Each protrusion 85 extends laterally from the end of the bottom portion 84a of each intake recess 84. The right protrusion 85 connects to the upper and lower wall-side flanges 82 of the second component 80 on the right side. The left protrusion 85 is also provided in the same manner as the right protrusion 85. The protrusions 85 guide air from outside the communication passage C into the interior space of the intake recess 84.

[0305] As described above, by providing the suction passage F in the vortex ring generating device 10, air in the air chamber S is pushed out by the operation of the drive unit 13, while air outside the connecting passage C is drawn into the first space I1. This suppresses pressure drop in the first space I1. As a result, the movable part 12 can move smoothly.

[0306] -Operational Actions-

[0307] Reference Figure 12 The basic operation of the vortex ring generating device 10 in this embodiment will be explained. It should be noted that... Figure 12 In the diagram, a solid line represents the state where the moving body M is in the reference position, and a double-dotted line represents the state where the moving body M is in the push-out position.

[0308] When the vortex ring generating device 10 is in operation, the drive unit 13 causes the movable body M to reciprocate in the front-to-back direction. Specifically, the shaft 96 connected to the drive unit 13 reciprocates in the front-to-back direction as driven by the drive unit 13. Furthermore, with the reciprocating motion of the shaft 96, all the movable planar parts 90 fixed on the shaft 96 become integral with the shaft 96 and reciprocate as well. The movable body M reciprocates between a reference position and a pushed-out position.

[0309] If the movable plane 90 of each air chamber unit A moves forward due to the drive of the drive unit 13 ( Figure 12 If the volume of each air chamber S decreases (as indicated by the double-dotted line), then the volume of each air chamber S decreases. If the volume of each air chamber S decreases, an air volume equal to the decrease in volume is pushed out of the air chamber S. The air pushed out of each air chamber S flows into the central passage C3 through the upper passage C1 and the lower passage C2 formed on the outer side of the cylinder 71. The air flowing into the central passage C3 flows toward the release port 55, and the vortex-shaped air is released from the release port 55.

[0310] like Figure 9 As shown by solid arrows, when the movable plane portion 90 of each air chamber unit A moves forward due to the drive unit 13, thereby pushing the air in each air chamber S forward, simultaneously, air outside the connecting passage C is drawn into the suction passage F. Specifically, if the movable plane portion 90 of each air chamber unit A moves forward, air outside the vortex ring generating device 10 flows in from the left and right protrusions 85 of the second component 80 and is drawn into the suction recesses 84 corresponding to each protrusion 85. The air drawn into the suction passage F flows into the first space I1 of the cylinder portion 71. In this way, the pressure in the first space I1 is prevented from decreasing as the air in the air chamber S is pushed out, allowing the movable plane portion 90 to move smoothly.

[0311] -Features of the fourth embodiment (1)-

[0312] In the vortex ring generating apparatus 10 of this embodiment, the movable body M has movable planar portions 90 and shaft portions 96 for all the air chamber units A. The shaft portion 96 is inserted into all the movable planar portions 90 and all the movable planar portions 90 are fixed to the shaft portion 96. Furthermore, the drive unit 13 is connected to the end of the shaft portion 96.

[0313] As a result, the structure of the moving body M becomes simple, and the amount of movement of the moving part 12 can be freely determined. Consequently, without increasing the number of moving parts 12 or increasing the area of ​​a single moving part 12, it is possible to increase the amount of air pushed out by each moving part 12, thus preventing the vortex ring generating device 10 from becoming too large.

[0314] Furthermore, since the vortex ring generating device 10 of this embodiment does not include an elastic support member 22 like the vortex ring generating device 10 of the first embodiment, the movement distance of the movable member 12 is not limited, and the movement amount of the movable member 12 can be increased compared with the structure of the first embodiment.

[0315] In addition, in the vortex ring generating apparatus 10 of the first embodiment, the deformation resistance of the elastic support member 22 is relatively large when the movable member 12 moves. In contrast, in the vortex ring generating apparatus 10 of this embodiment, the friction of the shaft portion 96 is relatively small. As a result, compared with the vortex ring generating apparatus of the first embodiment, the vortex ring generating apparatus 10 of this embodiment can move the movable body M with a smaller driving force. As a result, the load on the drive unit 13 is reduced.

[0316] Furthermore, in the vortex ring generating apparatus 10 of the first embodiment, since the movable member 12 is supported by the elastic support member 22, the elastic support member 22 may flex depending on the orientation of the vortex ring generating apparatus 10. If the elastic support member 22 flexes, the coil constituting the drive unit 13 will come into contact with the magnet, resulting in increased driving resistance or a contact sound. In contrast, in the vortex ring generating apparatus 10 of this embodiment, since all the movable planar parts 90 are fixed by the shaft part 96, the coil of the drive unit 13 is unlikely to come into contact with the magnet regardless of the orientation of the vortex ring generating apparatus 10. Therefore, the orientation of the vortex ring generating apparatus 10 can be freely determined.

[0317] -Features of the fourth embodiment (2)-

[0318] In the vortex ring generating apparatus 10 of this embodiment, the wall portion 81 has a suction recess 84 that connects the first space I1 of the cylinder portion 71 to the outside of the connecting passage C. Therefore, when air in the air chamber S is pushed out by the movable member 12, air from the outside of the connecting passage C is drawn into the first space I1. This prevents the pressure in the first space I1 from decreasing as the movable member 12 moves. As a result, the movable member 12 can move smoothly.

[0319] -Features of the fourth embodiment (3)-

[0320] In the vortex ring generating apparatus 10 of this embodiment, a connecting passage C is formed on the outer side of each cylinder 71 and communicates with the release port 55. Thus, air in the air chamber S of each air chamber unit A is released from the release port 55 to the outside of the vortex ring generating apparatus 10 via the connecting passage C formed on the outer side of the cylinder 71. Because the connecting passage C is formed on the outer side of the cylinder 71, a simple structure can be formed for the connecting passage C.

[0321] -Features of the fourth embodiment (4)-

[0322] In the vortex ring generating apparatus 10 of this embodiment, the movable plane portion 90 has a skeleton member 92 and a thin film 95 covering the surface of the skeleton member 92. As a result, compared with the case where the movable plane portion 90 is made of a flat plate, a lighter weight can be achieved.

[0323] -Features of the fourth embodiment (5)-

[0324] In this embodiment, the movable plane portion 90 of the vortex ring generating device 10 is formed in a circular shape. Therefore, even if the movable plane portion 90 rotates as driven by the drive unit 13, interference between the movable plane portion 90 and surrounding components can be suppressed.

[0325] -Features of the fourth embodiment (6)-

[0326] In the vortex ring generating apparatus 10 of this embodiment, the shaft portion 96 is supported by the beginning (frontmost) and end (rearmost) wall portions 81 via the shaft support member 98. As a result, by reducing the portion supporting the shaft portion 96, the shaft portion 96 can slide more smoothly.

[0327] - Variations of the fourth embodiment -

[0328] <Variation Example 1>

[0329] In the vortex ring generating device 10 of this embodiment, the movable flat portion 90 may also be formed as a flat plate.

[0330] <Variation Example 2>

[0331] In the vortex ring generating apparatus 10 of this embodiment, the cross-sectional areas of each air chamber unit A may be unequal. For example, the cross-sectional area of ​​each air chamber unit A may decrease as it approaches the front. Specifically, the cross-sectional area of ​​the stationary member 11 and the area of ​​the moving member 12 may also decrease as it approaches the front. In this case, the radial lengths of the upper passage C1 and the lower passage C2 increase as it approaches the front. As a result, the air resistance of the connecting passage C decreases as it approaches the front, thus facilitating airflow in the connecting passage C.

[0332] <Variation Example 3>

[0333] In the vortex ring generating apparatus 10 of this embodiment, the passage forming member 100 may be configured such that the radial lengths of the upper passage C1 and the lower passage C2 increase as they approach the front. As a result, the air resistance of the connecting passage C decreases as it approaches the front, thus making it easier for air to flow in the connecting passage C.

[0334] <Variation Example 4>

[0335] In the vortex ring generating apparatus 10 of this embodiment, multiple release ports 55 may also be formed on the front cover member 105 of the passage forming member 100. As a result, multiple vortex rings R can be released simultaneously from the vortex ring generating apparatus 10 as the drive unit 13 is driven.

[0336] <Variation Example 5>

[0337] In the vortex ring generating apparatus 10 of this embodiment, the cross-section of the air chamber unit A may be a shape other than a circle. For example, the cross-sectional shape of the air chamber unit A may be a polygon, such as a quadrilateral. Specifically, the longitudinal section of the stationary member 11 and the moving member 12 are formed as polygons. As a result, compared with the case where the cross-section of the air chamber unit A is formed as a circle, the area of ​​the movable plane portion 90 can be increased, thereby increasing the amount of air pushed out from the air chamber S.

[0338] <Variation Example 6>

[0339] In the vortex ring generating device 10 of this embodiment, a spring or a magnet may be arranged instead of the first buffer member 15 or the second buffer member 16. Therefore, by utilizing the reaction force of the spring or magnet, the sound generated when specified components come into contact with each other as the moving body M moves can be suppressed.

[0340] Other Implementation Methods

[0341] The above implementation method can also adopt the following structure.

[0342] In the vortex ring generating apparatus 10 described in the above embodiments, the vortex ring R may also contain a releasing component. The releasing component may be, for example, a fragrance component, water vapor, or a substance with a specified effect.

[0343] The embodiments and variations have been described above, but it should be understood that various changes can be made to the manner and details without departing from the spirit and scope of the claims. Appropriate combinations or substitutions can be made to the above embodiments, variations, and other embodiments as long as the function of the object of this disclosure is not affected.
