The invention provides a vortex ring generating device.

In the embodiment of the present invention, as shown in fig. 1 to 8, the vortex ring generating apparatus 100 includes a housing 110, an airflow pushing assembly 120 and a driving device 130. The casing 110 includes an air duct 111 and a flow collecting member 112, an air outlet 10 is disposed at one end of the air duct 111, the flow collecting member 112 is mounted at the air outlet 10, an air supply outlet 20 communicated with the air duct 111 is disposed on the flow collecting member 112, and an air passing area of the air supply outlet 20 is smaller than an air passing area of the air outlet 10. The airflow pushing assembly 120 is movably disposed in the housing 110. The driving device 130 includes a driving member 131, a transmission member 132, a reset member 133 and a damping assembly 134, the damping assembly 134 includes a first damping member 60 and/or a second damping member 50, the driving member 131 is installed on the housing 110 through the first damping member 60, one end of the transmission member 132 is connected to the airflow pushing assembly 120, the other end is connected to the driving member 131 through the second damping member 50, the driving member 131 drives the transmission member 132 to drive the airflow pushing assembly 120 to move toward one side of the housing 110, one end of the reset member 133 is connected to the housing 110, and the other end is connected to the airflow pushing assembly 120 to drive the airflow pushing assembly 120 to reset and move toward a direction opposite to a driving direction of the transmission member 132.

In this embodiment, the inner cavity of the housing 110 forms a vortex ring air duct, and the shape of the housing 110 may be a straight cylinder shape or a bent cylinder shape, and the cross section thereof may be a rectangular shape, a circular shape, an oval shape, a polygonal shape, an irregular shape, and the like, which is not limited herein. The overall shape and the cross-sectional shape of the vortex ring air duct can be selected according to the use requirement, and are not particularly limited herein. The overall shape of the airflow pushing assembly 120 is substantially matched with the shape of the inner cavity of the housing 110, and the size of the airflow pushing assembly 120 is slightly smaller than the cross-sectional size of the inner cavity of the housing 110, so that the airflow pushing assembly 120 can move in the housing 110 along the axial direction thereof. The airflow pushing assembly 120 is axially movable within the air duct 111. The airflow pushing assembly 120 may be a piston, a push plate, or a combination of a push plate and a film disposed on the periphery of the push plate, and only needs to push the airflow in the casing 110, so that the air supply opening 20 blows out the vortex ring, and the structure of the airflow pushing assembly 120 is not specifically limited herein. In order to facilitate the movement of the airflow pushing member 120 toward the side away from the air supply opening 20, ventilation openings may be formed in the bottom wall of the air duct 111 or the side wall adjacent to the bottom wall.

The shapes of the air outlet 10 and the air supply outlet 20 can be circular, rectangular, oval, polygonal, etc. The air duct 111 is substantially cylindrical. In one embodiment, as shown in fig. 1 and 2, the collecting member 112 is a collecting cover, and the collecting cover is disposed in a tapered manner from the air outlet 10 to the air blowing port 20. The cross-sectional shape of the manifold can be circular, oval, rectangular, etc. In order to reduce wind resistance, the collecting cover is substantially cylindrical. By making the collecting cover gradually decrease from the air outlet 10 to the air supply outlet 20, the collecting cover can collect the air from the air outlet 10, and the vortex ring can be generated and blown out more smoothly.

In another embodiment, the collecting member 112 is a collecting plate, and the collecting plate is installed at the air outlet 10 and is provided with an air supply outlet 20. The collecting plate may be a plate covering the air outlet 10, and the air outlet 20 smaller than the air outlet 10 is opened in the collecting plate, so that when the air flow is blown out from the air outlet 10 to the air outlet 20, the air flow blown out from the air outlet 20 can be made into a vortex shape due to a partial blocking effect of the collecting plate. And the collector plate has simple structure and is easy to manufacture and process. In other embodiments, the collector 112 may be formed by several plates, and the formation of a vortex ring may also be achieved by providing the supply air outlet 20 in one of the plates. The current collector 112 may also be formed by a combination of a current collector plate and a current collector cup,

the collecting member 112 and the air duct 111 may be integrally formed or may be separately formed. It can be understood that when the collecting member 112 is formed separately from the air duct 111, the collecting member 112 is hermetically connected to the air duct 111. When the collecting hood is integrally formed with the air duct 111, a virtual boundary is defined by using a joint of the air duct 111 and the collecting piece 112 as a boundary, one side of the virtual boundary is the air duct 111, the other side of the virtual boundary is the collecting piece 112, and the air outlet 10 of the air duct 111 is formed at the boundary. Clearly, the air outlet 10 has an air passing area larger than that of the air supply outlet 20 of the collecting member 112. The extension directions of the outer wall surfaces of the collecting piece 112 and the air duct 111 can be the same, that is, the length extension lines of the outer wall surfaces of the collecting piece and the air duct are in a straight line, and at the moment, the vortex ring air supply part is in a complete shape without a patch cord. The extending directions of the collecting piece 112 and the outer wall surface of the air duct 111 may be different, that is, the length extending lines of the outer wall surfaces of the collecting piece 112 and the air duct 111 form an included angle, and at this time, a junction line is formed at the junction of the collecting piece 112 and the air duct 111.

Since the air flow passing through the outlet 10 to the outlet 20 is smaller than the air flow passing through the outlet 10, a part of the air flow flowing from the outlet 10 to the outlet 20 flows along the inner wall surface of the flow collecting member 112 and then flows out from the periphery of the outlet 20, and the other part of the air flow flows out from the middle of the outlet 20. The partial flow flowing out from the edge of the supply port 20 is defined as edge flow, and the flow flowing out from the center of the supply port 20 is positioned as center flow. Then, the edge flow is subjected to resistance by the inner wall surface of the manifold 112. The flow velocity is lower compared to the middle stream. This difference in flow velocity will cause a vortex ring flow to occur as the air flows out of the supply opening 20. Under the same air quantity, the mode of vortex ring air supply can realize directional, fixed-point and remote air supply. And the vortex ring exchanges heat with ambient air in the transmission process, the temperature difference between the temperature of the vortex ring and the ambient air is not large, so that the vortex ring cannot generate obvious supercooling or overheating feeling when being blown on a person, and the comfort is improved.

As shown in fig. 2, 4 and 5, the first shock absorbing member 60 may be a rubber pad, a rubber block, a spring, a hydraulic damper, or the like. As shown in fig. 4 and 6, the second damper 50 may be a rubber bushing, a rubber coupling, a rubber connector, or the like. It can be understood that, when the damping assembly 134 includes the first damping member 60 and the second damping member 50, the driving member 131 is mounted on the housing 110 through the first damping member 60, so as to reduce the transmission of the vibration of the driving member 131 to the housing 110, and the driving member 131 is connected to the transmission member 132 through the second damping member 50, so as to reduce the transmission of the vibration of the driving member 131 to the transmission member 132, and at this time, the driving member 131 is isolated from the entire housing 110 by the damping members, so as to avoid rigid contact, and thus, the damping effect is optimal. When the damping assembly 134 includes only the first damping member 60, the driving member 131 is mounted to the housing 110 through the first damping member 60, and the driving member 131 is directly connected to the transmission member 132. When the shock absorbing assembly 134 includes only the second shock absorbing member 50, the driving member 131 and the transmission member 132 are connected through the second shock absorbing member 50, and the driving member 131 is directly mounted on the housing 110. Therefore, partial vibration of the driving element 131 can be isolated from being transmitted to the shell 110, and the effects of shock absorption and noise reduction can be achieved. The following description will exemplarily describe the damper assembly 134 including the first damper 60 and the second damper 50. The driving member 131 may be specifically mounted on the air duct 111, and in order to avoid the driving member 131 from affecting the movement of the airflow pushing assembly 120, the driving member 131 may be mounted on the outer side of the bottom wall surface of the air duct 111.

The driving member 131 may be a driving motor, a driving cylinder, an electromagnetic driving member 131, or the like. The restoring member 133 may be a magnetic member, a spring, or the like. The configuration of the transmission member 132 may be varied. In one embodiment, the driving member 131 is a driving motor, the transmission member 132 is a gear and a rack engaged with each other, the reset member 133 is a reset spring, one end of the rack is connected to the airflow pushing assembly 120, the gear is driven by the driving motor to drive the rack to move, so as to drive the airflow pushing assembly 120 to move towards the side away from the air supply opening 20, and the spring is used to realize the reset movement of the airflow pushing assembly 120 towards the side close to the air supply opening 20. In another embodiment, the driving member 131 is an electromagnetic driving member 131, the transmission member 132 is a push rod, one end of the push rod is connected to the airflow pushing assembly 120, and the other end of the push rod is connected to the electromagnetic driving member 131. The push rod is driven to reciprocate by the on-off of the electromagnetic driving element 131 so as to drive the push plate to reciprocate between the air supply opening 20 and the ventilation opening. In another embodiment, the driving member 131 is a driving motor, and the transmission member 132 is an eccentric wheel and a connecting rod, the eccentric wheel is disposed on the driving motor, one end of the connecting rod is connected to a rotating shaft of the eccentric wheel, and the other end of the connecting rod is connected to the push plate. Therefore, the connecting rod can drive the push plate to move back and forth.

When the vortex ring airflow needs to be pushed out, the driving element 131 drives the airflow pushing assembly 120 to move towards the side far away from the air supply opening 20, so that the side, close to the air supply opening 20, in the housing 110 is filled with air, then the driving element 131 drives the airflow pushing assembly 120 to move towards the side of the air supply opening 20 quickly, the airflow pushing assembly 120 pushes the airflow to be blown out from the air supply opening 20 quickly, and the vortex ring airflow can be blown out from the air supply opening 20 by enabling the air passing area of the air supply opening 20 to be smaller than the air passing area of the air outlet 10. This cycle makes it possible to periodically blow out the vortex ring airflow from the air outlet 20.

The vortex ring generating device 100 of the present invention makes the air passing area of the air supply opening 20 smaller than the air passing area of the air outlet 10, and the airflow pushing assembly 120 is movably disposed in the casing 110, and the driving device 130 drives the airflow pushing assembly 120 to reciprocate in the casing 110, so as to periodically push the airflow to be sent out from the air supply opening 20. The vortex ring airflow can be periodically output from the air supply opening 20, and the directional, fixed-point and remote air supply can be realized. Meanwhile, the damping unit 134 includes a first damping member 60 and/or a second damping member 50, the driving member 131 is mounted to the housing 110 through the first damping member 60, and the driving member 131 is connected to the transmission member 132 through the second damping member 50. Therefore, the driving element 131 is not in direct contact with the housing 110 and/or the transmission element 132, and rigid connection is avoided, so that the vibration of the driving element 131 can be effectively inhibited from being transmitted to the housing 110 and/or the transmission element 132, thereby reducing noise generated by the vibration of the driving element 131 and improving the use comfort of users.

In one embodiment, referring to fig. 4 and fig. 6, the driving member 131 is a driving motor, and the second damping member 50 is a flexible rubber sleeve, which is drivingly connected to an output shaft of the driving motor and one end of the transmission member 132. The soft rubber shaft sleeve can be a rubber shaft sleeve. The driving motor has the advantages of small volume, high transmission efficiency, low noise and the like. Make driving motor's drive shaft be connected with driving medium 132 through the flexible glue axle sleeve, on further reducing driving motor's vibration transmission to driving medium 132 under the condition that does not influence transmission efficiency to effectively reduce whole noise. At this time, the driving motor may be directly mounted to the housing 110 through the first damper 60.

In another embodiment, as shown in fig. 2, 4 and 6, the driving member 131 is a driving motor, the driving device 130 further includes a motor casing 135, the damping assembly 134 further includes a third damping member 70, the driving motor is mounted in the motor casing 135 through the third damping member 70, and the motor casing 135 is mounted in the air duct 111 through the first damping member 60. Third damper 70 can be rubber pad, rubber circle, rubber base etc. only need can isolated driving motor and motor casing 135's direct contact, and make driving motor through this third damper 70 firm installation to motor casing 135 in can. The driving motor is installed on the wind duct 111 through the motor casing 135, and compared with the driving motor directly installed on the wind duct 111, the driving motor is more convenient to install and detach, and the installation of the first shock absorbing member 60 is also convenient. And motor casing 135 plays the guard action for driving motor, avoids dust in the driving motor to pile up or get into the foreign matter and cause the card phenomenon of dying. Through setting up third damper 70 for driving motor installs in motor casing 135 through third damper 70 is indirect, then can avoid driving motor's vibration direct transfer to motor casing 135 on, causes motor casing 135's vibration and noise generation.

Specifically, referring to fig. 4, the third damping member 70 includes two rubber rings 71 disposed opposite to each other, and the two rubber rings 71 cover opposite sides of the driving motor and are installed in the motor casing 135.

In this embodiment, the two rubber rings 71 may cover the upper and lower sides, the left and right sides, or the front and rear sides of the driving motor. In order to make the installation of the driving motor more stable, two rubber rings 71 are tightly sleeved on two opposite sides of the driving motor, and then the rubber rings 71 are clamped in the motor casing 135. Thus, the rubber ring 71 is clamped between the driving motor and the inner wall surface of the casing 110, so that the driving motor is stably installed in the motor casing 135, and meanwhile, the vibration of the driving motor is effectively prevented from being transmitted to the motor casing 135. And two rubber rings 71 only wrap the opposite sides of the driving motor, so that the heat dissipation of the driving motor is not influenced while the installation requirement is met. In order to make the connection of rubber ring 71 and motor casing 135 more stable, can set up the arch on rubber ring 71, set up the draw-in groove on motor casing 135 for the protruding card of rubber ring 71 is established in the draw-in groove of motor casing 135. Of course, the third damping member 70 may also be a rubber sleeve, such that the driving motor is wrapped in the rubber sleeve, and only the driving shaft extends out of the rubber sleeve to be connected with the transmission member 132. In this manner, the transmission of the vibration of the drive motor to the motor case 135 can also be avoided.

On the basis of the above embodiment, as shown in fig. 2 and fig. 4, the motor casing 135 includes two first half shells 81 and two second half shells 82 connected to each other along a first direction, two rubber rings 71 cover two opposite sides of the driving motor along a second direction, and the first direction and the second direction form an included angle. Specifically, the first direction and the second direction are arranged perpendicularly. The first direction may be a vertical direction, a left-right direction, and a front-rear direction. The first half-shell 81 and the second half-shell 82 may be connected by means of screws, snaps, or the like. By splicing the motor casing 135 by the first half casing 81 and the second half casing 82, the mounting and dismounting of the driving motor in the motor casing 135 are facilitated. By making the first half-shell 81 and the second half-shell 82 spliced with each other in the first direction, the two rubber rings 71 wrap the opposite sides of the drive motor in the second direction. The first half shell 81, the second half shell 82 and the two rubber rings 71 surround the limit driving motor from different directions, so that the driving motor is more stably installed.

In an embodiment, referring to fig. 4, 5, 7 and 8, the first shock absorbing member 60 is a rubber foot pad, the motor casing 135 is provided with a clamping groove 80 for clamping the rubber foot pad, and the driving device 130 further includes a connecting member penetrating through the rubber foot pad to connect the motor casing 135 and the air duct 111. The number of the rubber pads may be plural, and the plural rubber pads are provided at intervals around the circumference of the motor case 135. So for motor casing 135 all can be installed on casing 110 through the rubber foot pad all around, improve motor casing 135's installation stability.

In the present embodiment, the number of the rubber foot pads may be three, four, six, etc. The rubber foot pad is clamped in the clamping groove 80 and then is installed on the housing 110. The connectors may be screws, bolts, etc. The rubber foot pad and the housing 110 are detachably mounted on the housing 110 through a connector, so that the motor casing 135 can be conveniently detached from and mounted on the housing 110. The motor casing 135 is fixed on the casing 110 through the rubber foot pad, and the vibration of the motor is reduced and transmitted to the casing 110 while the connection is stable, so that the vibration noise of the motor is effectively reduced.

On the basis of the above embodiment, as shown in fig. 4, an inner groove 61 adapted to the retaining groove 80 is provided on the side wall surface of the rubber foot pad, and when the rubber foot pad is retained in the retaining groove 80, the side wall surface of the inner groove 61 abuts against the outer wall surface of the motor casing 135.

The inner groove 61 is formed in the side wall surface of the rubber foot pad, so that the rubber foot pad is of a structure with three sides being open and wrapped, and two opposite wrapping surfaces and an outer wrapping surface are formed on the inner wall surface of the inner groove 61 of the rubber foot pad. When the motor casing 135 is mounted, the inner groove 61 is engaged with the retaining groove 80, and the two opposite wrapping surfaces are respectively abutted against the two opposite surfaces in the thickness direction of the motor casing 135, and the outer wrapping surface is abutted against the inner wall surface of the retaining groove 80. So, make the joint of rubber foot pad and motor casing 135 inseparabler stable.

In an embodiment, referring to fig. 2 and 3, the transmission member 132 includes a pulley 30 and a flexible belt 40, one end of the flexible belt 40 is fixed to the airflow pushing assembly 120, the other end of the flexible belt is fixed to the pulley 30, and the driving member 131 is connected to the pulley 30 through a second damping member 50 to drive the flexible belt 40 to drive the airflow pushing assembly 120 to move towards a side away from the air inlet 20; the reset member 133 drives the airflow urging member 120 to reset toward the side close to the air blowing opening 20.

In this embodiment, it is understood that the length of the flexible belt 40 should be greater than the moving stroke of the airflow pushing assembly 120, so as to pull the airflow pushing assembly 120 to gradually move away from the air outlet 20 when the airflow pushing assembly 120 is closest to the air outlet 20. The flexible band 40 refers to a band-like structure that can be easily deformed but is not easily broken. The flexible belt 40 may be made of cloth material such as nylon, cotton, and fiber, plastic material such as polyvinyl chloride, polyethylene, polypropylene, and polyester, and rubber material, or may be formed by splicing or mixing the above materials. To further improve the transmission effect, the flexible belt 40 may be a synchronous belt. The transmission is more accurate and stable, and the buffer damping capacity is realized, so that the noise is further reduced. One end of the flexible band 40 may be secured to the airflow-pushing assembly 120 by welding, snapping, screwing, bonding, or the like. The reset member 133 may be a compression spring, a magnetic member, or the like, which can drive the airflow pushing assembly 120 to move in a resetting manner.

The driving member 131 may be a driving motor, and the driving motor is exemplified below. One end of the flexible band 40 is fixed to the reel 30 so that the flexible band 40 can be wound on the winding surface of the reel 30. The driving shaft of the driving motor is fixedly connected with the reel 30 through the second shock absorbing member 50, and then the reel 30 is driven to rotate in the forward direction to wind the flexible belt 40 when the driving motor is electrified. When the driving motor is powered off, the reel 30 can rotate reversely under a smaller driving force, so that the flexible belt 40 can be stretched out of the reel 30 when the airflow push plate assembly moves again. Through setting up the line wheel 30, convolute flexible belt 40 on line wheel 30 for the coiling of flexible belt 40 is more regular, and difficult emergence skew, thereby easily the shrink and the extension of flexible belt 40. When the driving member 131 is operated, the driving force is greater than the restoring force of the restoring member 133, so that the flexible belt 40 can be wound by the pulley 30 to pull the airflow pushing assembly 120 to move toward the side away from the air blowing opening 20. When the driving element 131 stops working, the driving force disappears, and the restoring force of the restoring element 133 drives the airflow pushing assembly 120 to move to the side close to the air supply opening 20 quickly, and drives the flexible belt 40 to extend, so that the airflow pushing assembly 120 can move to and fro periodically along the axial direction of the casing 110.

Drive line wheel 30 through driving piece 131 and convolute flexible band 40 and drive air current and promote subassembly 120 and move towards the one side of keeping away from supply-air outlet 20, and driving piece 131 passes through second shock attenuation piece 50 with line wheel 30 and is connected, drive air current through piece 133 that resets and promote subassembly 120 and move towards the one side of being close to supply-air outlet 20, avoid driving piece 131 and the rigid contact of line wheel 30, and compare in rack and pinion's drive mode, turn into the flexible transmission with the rigid transmission, then can effectively reduce the vibration noise and the motion friction noise of vortex ring generating device 100, thereby user experience has greatly been promoted.

In one embodiment, as shown in fig. 2 and 3, the vortex ring generating apparatus 100 further includes a roller assembly 140, wherein the roller assembly 140 is mounted to one of the airflow pushing assembly 120 and the housing 110 and is in rolling engagement with the other of the airflow pushing assembly 120 and the housing 110, so that the airflow pushing assembly 120 can move along the axial direction of the housing 110.

It is understood that the roller assembly 140 may include one or more rollers to effect rolling, and of course, the roller assembly 140 may include a plurality of balls to effect rolling. The rollers or balls may be mounted directly to the airflow-propelling component 120 or the housing 110, or may be mounted via roller mounts. The roller assembly 140 and the airflow pushing assembly 120 or the housing 110 may be detachably mounted, such as clamped, screwed, and the like, or may be fixedly connected, such as welded, riveted, and the like.

When the roller assemblies 140 are installed at the periphery of the airflow pushing assembly 120, the roller assemblies 140 may be arranged in multiple groups, and the multiple groups of roller assemblies 140 are in rolling fit with the inner wall surface of the housing 110, so that the airflow pushing assembly 120 is in rolling connection with the housing 110 through the roller assemblies 140. That is, the airflow pushing assembly 120 can roll within the housing 110 in the axial direction of the housing 110. Therefore, on one hand, since the friction between the airflow pushing assembly 120 and the casing 110 is rolling friction, compared with the sliding friction between the periphery of the airflow pushing assembly 120 and the casing 110, the friction force is greatly reduced, the sliding friction is converted into rolling friction, and the movement noise is reduced, so that the overall movement noise of the vortex ring generating device 100 is low; on the other hand, since the circumferential direction of the airflow pushing assembly 120 contacts the inner wall surface of the housing 110 through the roller assembly 140, the roller assembly 140 can also play a role in guiding the axial movement of the airflow pushing assembly 120, so that the sliding friction between the guide bar and the housing 110 is converted into rolling friction compared with the guiding through the guide bar, and the noise is further reduced.

When the roller assembly 140 is mounted on the housing 110, a plurality of rows of rollers or balls may be disposed on the housing 110 corresponding to the moving stroke of the airflow pushing assembly 120, each row of rollers or balls is distributed along the circumferential direction of the housing 110 at intervals, and a gap between two adjacent rows of balls or balls is smaller than or equal to the thickness of the airflow pushing assembly 120, so that the airflow pushing assembly 120 has rolling friction with the housing 110 when moving along the axial direction of the housing 110, and the airflow pushing assembly 120 is prevented from being clamped between two adjacent rows of rollers or balls. The sliding friction can be converted into rolling friction, and the overall noise is reduced.

In one embodiment, the airflow pushing assembly 120 includes a pushing plate and a guiding rod, one end of the guiding rod is connected to the pushing plate, and the other end is connected to the housing 110 by the roller assembly 140. It will be appreciated that when the airflow pushing assembly 120 moves within the housing 110, i.e., when the guide bar moves within the roller assembly 140, a portion of the guide bar is disposed outside the roller assembly 140, and sufficient space is required to accommodate the extended guide bar. The through hole can be arranged on the bottom wall of the air duct 111 so that the guide rod can penetrate through the through hole. Of course, it is also possible that the roller assembly 140 is disposed in the air duct 111 at a position adjacent to the bottom wall surface of the air duct 111, and a moving space for the guide bar to move is provided between the roller assembly 140 and the bottom wall of the air duct 111. At this time, the roller assembly 140 may be mounted on the air duct 111 through a bracket. The roller assembly 140 is mounted on the housing 110, and the roller assembly 140 can roll along the length direction of the guide rod, i.e. when the airflow pushing assembly 120 reciprocates in the housing 110 along the axial direction, rolling friction exists between the guide rod and the housing 110. Compared with the guide rod directly connected with the shell 110 in a sliding manner, the friction force between the guide rod and the shell 110 is reduced, so that the guide rod can move back and forth more smoothly, and the noise is effectively reduced.
