The utility model provides a vortex ring generating device.

In the embodiment of the present invention, as shown in fig. 1 to 7, the vortex ring generator 100 includes a housing 110, an airflow pushing assembly 120, a driving device 130 and a magnetic assembly. 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 reciprocally disposed in the casing 110, and has a first position close to the air outlet 20 and a second position far from the air outlet 20. The driving device 130 is used for driving the airflow pushing assembly 120 to reciprocate between the first position and the second position, so as to periodically push the airflow to be blown out from the air blowing opening 20. The magnetic assembly includes a first magnetic member 141 and a second magnetic member 142, the first magnetic member 141 is mounted on the airflow pushing assembly 120, and the second magnetic member 142 is mounted on the casing 110 between the air outlet 20 and the first position, so as to generate a repulsive force toward the second position for the first magnetic member 141 when the driving device 130 drives the airflow pushing assembly 120 to move from the second position to the first position.

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.

By moving the airflow pushing member 120 back and forth between the first position and the second position, the airflow pushing member 120 gradually moves away from the air outlet 20 when moving from the first position to the second position, so that the side of the casing 110 close to the air outlet 20 is filled with air, and then the airflow pushing member 120 rapidly moves from the second position to the first position, so as to squeeze the air in the casing 110 and send out the vortex ring airflow from the air outlet 20.

The structure of the driving device 130 may be various. In one embodiment, the driving device 130 includes an electromagnetic driving element 131 and a push rod, one end of which is connected to the airflow pushing assembly 120, and the other end of which is connected to the electromagnetic driving element 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 device 130 includes a driving motor, a gear and a rack engaged with each other, one end of the rack is connected to the airflow pushing assembly 120, and the driving motor drives the gear to drive the rack to move, thereby driving the airflow pushing assembly 120 to reciprocate. It is also possible that the motor drives the airflow pushing assembly 120 to move only to the side far away from the air supply opening 20, and the elastic restoring member 134 is used to restore the airflow pushing assembly 120 to move to the side near the air supply opening 20. In yet another embodiment, the driving device 130 includes a driving motor, a worm ring and a worm screw, which are engaged with each other, one end of the worm screw is connected to the push plate, and the other end is connected to the worm wheel, and the worm wheel is fixedly installed with a driving shaft of the driving motor. The worm is driven to reciprocate by the driving motor to drive the worm to reciprocate, and further drive the push plate to reciprocate between the air supply outlet 20 and the scavenging port. In another embodiment, the driving device 130 includes a driving motor, an eccentric wheel disposed on the driving motor, and a connecting rod having one end connected to a rotating shaft of the eccentric wheel and the other end connected to the push plate. Therefore, the connecting rod can drive the push plate to move back and forth.

The first magnetic member 141 and the second magnetic member 142 may have the same shape, size, and number, or may be different. The first magnetic element 141 and the second magnetic element 142 may be magnetic elements, such as a circular magnetic element and a square magnetic element, and the first magnetic element 141 and the second magnetic element 142 may also be magnetic elements, such as a rectangular magnetic element and an arc magnetic element. By making the first magnetic member 141 and the second magnetic member 142 arc-shaped magnetic strips, the arc-shaped magnetic strips are matched with the arc-shaped periphery of the housing 110 and the airflow pushing assembly 120, so as to maintain the consistency of the overall appearance. The first magnetic member 141 and the second magnetic member 142 may be permanent magnets or electromagnets. In order to simplify the structure and save the cost, the first magnetic member 141 and the second magnetic member 142 are preferably permanent magnets. The first magnetic member 141 may be adhered to the airflow pushing assembly 120 by using glue, or a groove may be formed in the airflow pushing assembly 120 to embed the first magnetic member 141 in the groove. The second magnetic member 142 may be directly attached to the inner wall surface of the casing 110, or an attachment structure may be provided on the inner wall surface of the casing 110 to attach the second magnetic member 142.

It can be understood that the opposite ends of the first magnetic member 141 and the second magnetic member 142 have the same magnetic pole. The first magnetic member 141 and the second magnetic member 142 repel each other when they approach each other, so as to generate a repulsive force to the airflow pushing assembly 120. In order to ensure that the first magnetic member 141 and the second magnetic member 142 generate a repulsive force, the first magnetic member 141 and the second magnetic member 142 should be disposed at corresponding positions. The second magnetic member 142 is mounted on the housing 110 between the air supply opening 20 and the first position, so that when the airflow pushing assembly 120 moves from the second position to a side close to the air supply opening 20 to a position close to the second magnetic member 142, the second magnetic member 142 generates a repulsive force to the first magnetic member 141 toward the second position, and when the airflow pushing assembly 120 moves to the first position, the repulsive force is equal to a driving force for driving the airflow pushing assembly 120 to move toward the side close to the air supply opening 20, so that the airflow pushing assembly 120 stops at the first position. The number and size of the second magnetic member 142 and the first magnetic member 141 may be designed according to the distance between the first position and the installation position of the second magnetic member 142, and are not particularly limited herein.

The utility model discloses a make the overfire air area of supply-air outlet 20 be less than the overfire air area of air outlet 10, and the air current promotes subassembly 120 and locate casing 110 with reciprocating motion, and have the first position that is close to supply-air outlet 20 and keep away from the second position of supply-air outlet 20, drive arrangement 130 drive air current promotes subassembly 120 reciprocating motion between first position and second position to periodic promotion air current is seen off from supply-air outlet 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, a first magnetic member 141 is disposed on the airflow pushing assembly 120, and a second magnetic member 142 is disposed on the casing 110 between the air blowing opening 20 and the first position, so that when the driving device 130 drives the airflow pushing assembly 120 to move from the second position to the first position, a repulsive force toward the second position is generated on the first magnetic member 141. Such that the airflow urging assembly 120 is subjected to a repulsive force when moving from the second position to the first position, thereby stopping the movement. The stopping and limiting manner does not need to make the airflow pushing assembly 120 directly touch other media, thereby avoiding the generation of noise and improving the use comfort of users.

Specifically, as shown in fig. 2 to 7, the airflow pushing assembly 120 includes a push plate movably disposed in the air duct 111, the first magnetic member 141 is mounted on the push plate, and the second magnetic member 142 is mounted on the current collector 112. The second magnetic member 142 is disposed in the current collector 112, and the first position and the second position where the push plate moves are both located in the air duct 111, so that the overall structure is more compact. Of course, the first position and the second magnetic member 142 may also be both located in the current collector 112 or in the wind barrel 111.

In addition to the above embodiments, referring to fig. 4 and 6, the inner wall surface of the current collector 112 is provided with a mounting boss 30, and the second magnetic member 142 is mounted on the mounting boss 30 and is disposed toward the push plate. The mounting bosses 30 may be annular bosses circumferentially around the collector 112 or may be a plurality of bosses spaced circumferentially around the collector 112. Through installing second magnetic member 142 on installation boss 30, and set up towards the push pedal, compare in with second magnetic member 142 direct mount on the internal wall face of collecting flow piece 112, when not influencing the structural strength of collecting flow cover for the installation of second magnetic member 142 is more stable, and second magnetic member 142 is bigger to the area of action of first magnetic member 141, and then the repulsion force is bigger.

Specifically, as shown in fig. 4, the mounting boss 30 is provided with a mounting groove 31 at a side facing the push plate, and the second magnetic member 142 is embedded in the mounting groove 31. The second magnetic member 142 is embedded in the mounting groove 31 of the mounting boss 30, so that the second magnetic member 142 is more stably mounted. In other embodiments, the second magnetic member 142 can also be bonded to the side of the mounting boss 30 facing the pusher plate.

In an embodiment, as shown in fig. 2 to 7, the first magnetic member 141 is disposed on a side of the push plate facing the air outlet 20 and is disposed corresponding to the second magnetic member 142. In this way, compared with the arrangement of the first magnetic member 141 on the side of the push plate facing away from the air supply outlet 20, the acting force between the first magnetic member 141 and the second magnetic member 142 is greater, so that the thrust airflow pushing assembly 120 is more effective. In other embodiments, the first magnetic member 141 may be disposed on a side of the push plate facing away from the air blowing port 20.

In an embodiment, referring to fig. 2, fig. 3, fig. 5 and fig. 7, the first magnetic members 141 are multiple, and the multiple first magnetic members 141 are disposed at intervals around the circumference of the airflow pushing assembly 120. The first magnetic member 141 may be a magnetic block or a magnetic strip. By arranging the plurality of first magnetic members 141 at intervals around the circumference of the airflow pushing assembly 120, the overall weight of the airflow pushing assembly 120 is reduced on the premise of meeting the requirement of repulsion force, so that the driving force for pushing the airflow pushing assembly 120 to move is reduced, and the weight of the whole machine is lighter.

In another embodiment, the number of the first magnetic members 141 is one, and the first magnetic members 141 are disposed around the circumference of the airflow pushing assembly 120. At this time, the first magnetic member 141 is an annular magnetic stripe. The magnetic force acting area of the first magnetic member 141 is increased, so that the repulsive force between the first magnetic member 141 and the second magnetic member 142 is larger, and the stopping effect on the airflow pushing assembly 120 is better. And the first magnetic member 141 is disposed around the circumferential direction of the airflow pushing assembly 120, and can correspond to the second magnetic member 142 disposed on the inner wall surface of the casing 110, so as to further enhance the acting force therebetween.

In one embodiment, as shown in fig. 4 and 6, the second magnetic member 142 is multiple, and the multiple second magnetic members 142 are arranged at intervals around the circumference of the housing 110. The second magnetic member 142 may be a magnetic block or a magnetic strip. By arranging the plurality of second magnetic members 142 at intervals around the circumference of the housing 110, the overall weight of the housing 110 is reduced on the premise that the requirement of the repulsive force is satisfied, so that the overall weight is lighter.

In another embodiment, the second magnetic member 142 is disposed around the circumference of the housing 110. At this time, the second magnetic member 142 is an annular magnetic stripe. The magnetic force acting area of the second magnetic member 142 is increased, so that the repulsive force between the first magnetic member 141 and the second magnetic member 142 is larger, and the stopping effect on the airflow pushing assembly 120 is better. And the second magnetic member 142 is disposed around the circumference of the housing 110, the influence of the second magnetic member 142 on the vortex ring airflow is also reduced in the case that the repulsive force toward the second position is generated to the first magnetic member 141.

In an embodiment, referring to fig. 2, 3, 5 and 8, the vortex ring generating apparatus 100 further includes a roller assembly 150, wherein the roller assembly 150 is mounted on one of the airflow pushing assembly 120 and the housing 110 and is in rolling fit 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 150 may include one or more rollers to effect rolling, although the roller assembly 150 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 150 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 150 are installed at the periphery of the airflow pushing assembly 120, the roller assemblies 150 may be arranged in multiple groups, and the multiple groups of roller assemblies 150 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 150. 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 150, the roller assembly 150 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 150 is installed 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 when the airflow pushing assembly 120 moves along the axial direction of the housing 110, the airflow pushing assembly 120 is in rolling friction with 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 150. 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 150, a portion of the guide bar is disposed outside the roller assembly 150, and sufficient space is required to accommodate the extended guide bar. The through hole b can be arranged on the bottom wall of the air duct 111 so that the guide rod can penetrate through the through hole b. Of course, it is also possible that the roller assembly 150 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 150 and the bottom wall of the air duct 111. At this time, the roller assembly 150 may be mounted on the air duct 111 through a bracket. The roller assembly 150 is mounted on the housing 110, and the roller assembly 150 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.

In this embodiment, it is understood that the length of the flexible belt 133 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 133 refers to a band-like structure that can be easily deformed but is not easily broken. The flexible belt 133 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.

One end of the flexible band 133 is fixed to the reel 132 so that the flexible band 133 can be wound on the winding surface of the reel 132. The driving shaft of the driving motor is fixedly connected with the reel 132, and then the driving motor drives the reel 132 to rotate in the forward direction to wind the flexible belt 133 when being electrified. When the driving motor is powered off, the reel 132 can rotate reversely under a smaller driving force, so that the flexible belt 133 can extend out of the reel 132 when the airflow push plate assembly moves again. By providing the pulley 132, the flexible belt 133 is wound around the pulley 132, so that the winding of the flexible belt 133 is more regular and less prone to deviation, and the flexible belt 133 is easy to contract and extend. When the driving member 131 is operated, the driving force is greater than the reset force of the reset member 134, so that the flexible belt 133 can be wound by the reel 132 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 134 drives the airflow pushing assembly 120 to move to the side close to the air supply outlet 20 in a restoring manner, and simultaneously drives the flexible belt 133 to extend, so that the airflow pushing assembly 120 can move to and fro periodically along the axial direction of the housing 110.
