The invention provides a vortex ring generating device.

In the embodiment of the present invention, as shown in fig. 1 to 3, the vortex ring generating device 100 includes a housing 110, an airflow pushing assembly 120, a driving device 130 and a restoring member 140. The casing 110 includes an air duct 111 and a flow collecting member 112, one end of the air duct 111 is provided with a first air outlet 10, the flow collecting member 112 is installed at the first air outlet 10, the flow collecting member 112 is provided with an air supply opening 30 communicated with the air duct 111, and an air passing area of the air supply opening 30 is smaller than an air passing area of the first air outlet 10. The airflow pushing assembly 120 is movably disposed in the casing 110 to periodically push the airflow to be blown out from the air blowing opening 30. The driving device 130 includes a driving member 131 and a flexible belt 132, one end of the flexible belt 132 is fixed to the airflow pushing assembly 120, and the other end is fixed to the driving member 131, the driving member 131 is used to drive the flexible belt 132 to drive the airflow pushing assembly 120 to move toward a side away from the air outlet 30. The reset member 140 has one end connected to the airflow pushing member 120 and the other end connected to the housing 110, so as to drive the airflow pushing member 120 to move toward the side close to the air outlet 30.

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 30 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 to the side far away from the air supply opening 30, 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 first outlet 10 and the supply-air outlet 30 may be circular, rectangular, oval, polygonal, etc. The air duct 111 is substantially cylindrical. In one embodiment, the flow collecting member 112 is a flow collecting cover, and the flow collecting cover is gradually tapered from the air outlet to the air outlet 30. 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 flow collecting cover gradually decrease from the air outlet to the air supply outlet 30, the flow collecting cover can collect the flow of the air discharged from the air outlet, and the generation and blowing of the vortex ring are smoother.

In another embodiment, the collecting member 112 is a collecting plate, and the collecting plate is installed at the first air outlet 10 and has an air inlet 30. The collecting plate may be a plate covering the first outlet 10, and the air outlet 30 smaller than the outlet is formed in the collecting plate, so that when the air flow is blown out from the outlet to the air outlet 30, the air flow blown out from the air outlet 30 may be in a vortex ring 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 30 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 an air outlet of the air duct 111 is formed at the boundary. Clearly, the air outlet has an air flow area greater than the air supply outlet 30 of the collector 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 area of the air blowing port 30 is smaller than the air flow area of the first air outlet 10, a part of the air flow flowing from the first air outlet 10 to the air blowing port 30 flows along the inner wall surface of the collecting member 112 and then flows out from the periphery of the air blowing port 30, and the other part of the air flow flows out from the middle of the air blowing port 30. The partial flow flowing out from the edge of the supply port 30 is defined as edge flow, and the flow flowing out from the center of the supply port 30 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 30. 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.

It will be appreciated that the length of the flexible band 132 should be greater than the travel of the airflow pushing assembly 120 so as to pull the airflow pushing assembly 120 gradually away from the air supply opening 30 when the airflow pushing assembly 120 is closest to the air supply opening 30. The flexible strap 132 refers to a strap-like structure that can be easily deformed but is not easily broken. The flexible belt 132 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 enhance the transmission effect, the flexible belt 132 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 strap 132 may be secured to the airflow-pushing assembly 120 by welding, snapping, screwing, bonding, etc.

The driving member 131 may be a driving cylinder, a driving motor, etc., and the driving motor has advantages of small volume, easy control, etc., and is exemplified by the driving motor. The flexible belt 132 can be directly wound on the driving shaft of the driving motor, or the flexible belt 132 can be fixed on the pulley 133 by arranging the pulley 133 connected with the driving motor, so as to drive the flexible belt 132 to be wound on the pulley 133. The restoring member 140 may be a compression spring. At this time, one end of the compression spring is connected to the airflow pushing assembly 120, and the other end is connected to the housing 110. When the airflow pushing assembly 120 is pulled by the flexible belt 132 to move to the side far away from the air supply opening 30, the compression spring is pressed, and when the driving motor is powered off, the compression spring is elastically restored, so that the airflow pushing assembly 120 is driven to rapidly move to the side close to the air supply opening 30, and then the vortex ring airflow is pushed out. The reset element 140 may also be two magnetic elements that repel each other, in which case one magnetic element is disposed on the airflow pushing assembly 120 and the other magnetic element is disposed on the bottom wall of the air duct 111. When the driving motor is powered on, the driving shaft of the driving motor rotates to wind the flexible belt 132, and the driving force is greater than the repulsive force between the two magnetic members, thereby pulling the airflow pushing assembly 120 to a position far away from the air blowing opening 30. When the driving motor is powered off, the driving force disappears, and the repulsive force of the two magnetic members pushes the airflow pushing assembly 120 to a position close to the air supply opening 30, so that the vortex ring airflow is rapidly blown out from the air supply opening 30.

When the vortex ring airflow needs to be pushed out, the driving element 131 shrinks the flexible belt 132 through winding, so as to drive the airflow pushing assembly 120 to move towards the side far away from the air supply opening 30, then the driving element 131 stops working, the resetting element 140 drives the airflow pushing assembly 120 to move towards the side close to the air supply opening 30, the airflow pushing assembly 120 pushes the airflow to be blown out from the air supply opening 30 quickly, and the vortex ring airflow can be blown out from the air supply opening 30 by enabling the air passing area of the air supply opening 30 to be smaller than the air passing area of the air outlet. This cycle makes it possible to periodically blow out the vortex ring airflow from the air blowing port 30.

The vortex ring generating device 100 of the present invention can periodically output vortex ring airflow from the air supply opening 30 by making the air passing area of the air supply opening 30 smaller than the air passing area of the first air outlet 10, and the airflow pushing assembly 120 is movably disposed in the housing 110 to periodically push the airflow to be blown out from the air supply opening 30, so that directional, fixed-point and remote air supply can be realized. Simultaneously, drive flexible band 132 through driving piece 131 and drive airflow and promote subassembly 120 and remove towards the one side of keeping away from supply-air outlet 30, drive airflow through piece 140 that resets and promote subassembly 120 and remove towards the one side that is close to supply-air outlet 30, compare in the drive mode of rack and pinion, turn into the flexible transmission with rigid transmission, then can effectively reduce the vibration noise and the motion friction noise of vortex ring generating device 100 to user's use experience has greatly been promoted.

In practical applications, referring to fig. 4, the driving device 130 further includes a pulley 133, one end of the flexible belt 132 is connected to the pulley 133, the driving element 131 is connected to the pulley 133 to drive the pulley 133 to wind the flexible belt 132 when the driving element 131 works, so as to drive the airflow pushing assembly 120 to move towards the side away from the air blowing opening 30, and when the driving element 131 stops working, the resetting element 140 drives the airflow pushing assembly 120 to reset towards the side close to the air blowing opening 30 to move, and drives the flexible belt 132 to extend from the pulley 133.

In the present embodiment, one end of the flexible band 132 is fixed to the reel 133 so that the flexible band 132 can be wound on the winding surface of the reel 133. The driving shaft of the driving motor is fixedly connected with the reel 133, and then the driving motor drives the reel 133 to rotate in the forward direction to wind the flexible belt 132 when being electrified. When the driving motor is powered off, the reel 133 can rotate reversely under a smaller driving force, so that the flexible belt 132 can be extended out of the reel 133 when the airflow push plate assembly moves in a resetting manner. By providing the pulley 133, the flexible belt 132 is wound around the pulley 133, so that the winding of the flexible belt 132 is more regular and less prone to deviation, and the flexible belt 132 is easily contracted and extended. When the driving member 131 is operated, the driving force is greater than the reset force of the reset member 140, so that the flexible belt 132 can be wound by the reel 133 to pull the airflow pushing assembly 120 to move toward the side away from the air blowing opening 30. When the driving element 131 stops working, the driving force disappears, and the restoring force of the restoring element 140 drives the airflow pushing assembly 120 to move to the side close to the air supply opening 30 in a restoring manner, and simultaneously drives the flexible belt 132 to extend, so that the airflow pushing assembly 120 can move to and fro periodically along the axial direction of the housing 110.

In one embodiment, as shown in fig. 3 and 6, the airflow pushing assembly 120 includes a pushing plate, and one end of the flexible belt 132 is connected to the middle of the pushing plate, and the other end is tangent to the winding surface of the pulley 133. One end fixed connection of flexible band 132 is in the middle part of push pedal, then when line wheel 133 convolutes flexible band 132, can stimulate the middle part of push pedal to make the holistic atress of push pedal more even, and then make the push pedal more steady in the removal under the traction of flexible band 132. The other end of the flexible belt 132 is connected to the reel 133, and the flexible belt 132 is tangent to the winding surface of the reel 133, so that the winding surface of the reel 133 of the flexible belt 132 is wound. Therefore, the flexible belt 132 is wound more neatly, and the moving stability of the push plate is further improved.

On the basis of the above embodiment, further, the vortex ring generating device 100 further includes a flexible belt fixing plate 150, the flexible belt fixing plate 150 is detachably mounted on a side of the push plate facing away from the air supply outlet 30, and one end of the flexible belt 132 is fixed to the flexible belt fixing plate 150.

In this embodiment, the flexible band fixing plate 150 may be detachably connected to the push plate by means of screws, snaps, or the like. The flexible belt 132 is fixed on the push plate through the flexible belt fixing plate 150, which facilitates the disassembly and assembly of the flexible belt 132 on one hand and makes the connection of the flexible belt 132 more stable on the other hand.

In one embodiment, referring to fig. 4, the pulley 133 includes a first half-shell 40 and a second half-shell 50 that are radially spliced together, and one end of the flexible band 132 is pressed between the first half-shell 40 and the second half-shell 50. It can be understood that the first half-shell 40 and the second half-shell 50 may be half of the entire pulley 133, or one of the first half-shell 40 and the second half-shell 50 may be larger than half of the pulley 133, and the other one may be smaller than half of the pulley 133, so that the first half-shell 40 and the second half-shell 50 are spliced together in the radial direction to form the entire pulley 133. The first half-shell 40 and the second half-shell 50 can be detachably spliced by means of screws, buckles, magnetic attraction and the like. By crimping one end of the flexible band 132 between the first half shell 40 and the second half shell 50, the connection stability of the flexible band 132 to the pulley 133 is improved, and in addition, one end of the flexible band 132 is made detachable, thereby facilitating the replacement and adjustment of the flexible band 132. The flexible strap 132 may be crimped at the joint of the first half shell 40 and the second half shell 50.

In addition to the above embodiment, a first concave-convex portion 41 is provided at a joint of the first half shell 40 facing the second half shell 50, a second concave-convex portion 51 adapted to the first concave-convex portion 41 is provided at a joint of the second half shell 50 facing the first half shell 40, and one end of the flexible band 132 is pressed between the first concave-convex portion 41 and the second concave-convex portion 51. It will be appreciated that the middle portions of the first and

second half shells

40, 50 may be hollow or solid. The joint surface of the first half-shell 40 and the second half-shell 50 may be only the edge of the half-shells, or may include the end surface of the middle portion thereof. By providing the first concave-convex portion 41 at the joint of the first half shell 40, providing the second concave-convex portion 51 on the second half shell 50, which is engaged with the first concave-convex portion 41, and pressing one end of the flexible belt 132 between the first concave-convex portion 41 and the second concave-convex portion 51, after the first half shell 40 and the second half shell 50 are jointed, the contact surface and the friction force between the flexible belt 132 and the half shells are increased, so that the flexible belt 132 is more tightly and stably fixed on the pulley 133.

In one embodiment, as shown in FIG. 5, at least one end of the flexible strap 132 is provided with a reinforcing member 134 for fixedly mounting the flexible strap 132. The reinforcement 134 may be a rigid structure such as a metal sheet or a plastic sheet. By providing the end portion of the flexible belt 132 with the reinforcing member 134, the strength and rigidity of the end portion of the flexible belt 132 can be increased, so that the end portion of the flexible belt 132 can be more easily fixed to the airflow pushing assembly 120 and the pulley 133.

In an embodiment, referring to fig. 6, the vortex ring generating device 100 further includes a guide rod 160 extending along an axial direction of the air duct 111, one end of the guide rod 160 is connected to the airflow pushing assembly 120, a guide hole for the other end of the guide rod 160 to penetrate is formed in a bottom wall of the air duct 111, the reset element 140 is a compression spring, and an extending direction of the guide rod 160 is consistent with an extending direction of the compression spring.

In this embodiment, the number of the guide rods 160 may be one or more, the number of the compression springs may be one or more, and the number of the guide rods 160 and the number of the compression springs may be the same or different.
