Referring to fig. 1 to 6, the present invention provides a vortex ring generator 100, wherein the vortex ring generator 100 includes a housing 110, a vortex ring generator 140 and a driving device 150. The casing 110 includes an air duct 120 and a flow collecting member 130, wherein one end of the air duct 120 is provided with a first air outlet 122, the flow collecting member 130 is installed at the first air outlet 122, the flow collecting member 130 is provided with an air supply outlet 131 communicated with the air duct 120, and an air passing area of the air supply outlet 131 is smaller than an air passing area of the first air outlet 122. A vortex ring generator 140 is installed in the housing 110, and the vortex ring generator 140 includes a vortex ring generator that periodically drives an air flow to be blown out through the air blowing port. The driving device 150 includes a motor 151, a crank 152 and a connecting rod 154, the motor 151 is mounted on the housing 110, one end of the crank 152 is connected to a motor shaft of the motor 151, the other end of the crank 152 is movably connected to one end of the connecting rod 154, and the other end of the connecting rod 154 is movably connected to the vortex ring generator; the motor 151 periodically drives the connecting rod 154 to move back and forth along the axial direction of the air duct 120 through the crank 152, so as to drive the vortex ring generator to move back and forth.

In the embodiment of the present invention, the air duct 120 is substantially cylindrical. The air duct 120 includes a bottom wall surface and a peripheral wall surface, a first air inlet 121 is disposed on the bottom wall surface and/or the peripheral wall surface, and a first air outlet 122 is disposed at one end of the air duct 120. The collecting member 130 is installed at the first air outlet 122, and the collecting member 130 is connected to the air duct 120, it is to be understood that, for convenience of assembly and disassembly, the collecting member 130 and the air duct 120 may be integrally formed, or may be separately formed, such as being clamped and screwed.

There are various structures of the current collector 130, and there is no particular limitation thereto. For example, the collecting member 130 is a collecting barrel, and the collecting barrel is tapered from the first air outlet 122 to the air supply outlet 131, so that the air passing area of the air supply outlet 131 is smaller than the air passing area of the first air outlet 122. For another example, the collecting member 130 is a collecting plate, the collecting plate is disposed at the first air outlet 122, and the air supply opening 131 is opened on the collecting plate, so that the air passing area of the air supply opening 131 may be smaller than the air passing area of the first air outlet 122.

Since the air flow area of the air blowing port 131 is smaller than that of the air outlet, a part of the air flow flowing from the air outlet to the air blowing port 131 flows along the inner wall surface of the collecting member 130 and then flows out from the periphery of the air blowing port 131, and the other part of the air flow flows out from the middle of the air blowing port 131. The partial flow flowing out from the edge of the air blowing opening 131 is defined as edge flow, and the flow flowing out from the middle of the air blowing opening 131 is positioned as middle flow. Then, the edge flow is subjected to resistance by the inner wall surface of the manifold 130. The flow velocity is lower compared to the middle stream. This difference in flow velocity causes a vortex ring airflow to be generated when the airflow exits the supply opening 131. 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.

For example, in this embodiment, the vortex ring generator includes a flexible member 141 and a push plate 144, an outer edge of the flexible member 141 is connected to an inner peripheral wall of the housing 110, the push plate 144 is mounted on the flexible member 141, and the other end of the connecting rod is movably connected to the push plate. In this embodiment, the vortex ring generator includes a flexible member 141 and a push plate 144, which can reduce noise generation and rapidly drive the vortex ring generator to move back and forth.

The outer circumference of the flexible member 141 is connected with the inner circumference wall of the casing 110 in a sealing manner, and in particular, the outer circumference of the flexible member 141 may be connected with the inner circumference wall of the air duct 120 in a sealing manner, and may also be connected with the outer circumference wall of the collecting member 130 in a sealing manner. The flexible member 141 may be connected to the housing 110 by means of screws, bonding, crimping, etc., and the connection manner is not limited herein. The flexible member 141 may be disposed in the air duct 120 or the manifold 130 or a connection between the air duct 120 and the manifold 130. In order to make the moving path of the push plate 144 longer and the compression effect better, the flexible member 141 may be disposed in the air duct 120 near the first air outlet 122. The push plate 144 has a plate-like structure, and in order to enable the push plate 144 to better move the flexible member 141, the push plate 144 may be installed in the middle of the flexible member 141, but is not limited thereto. In addition, the push plate 144 can be fixed to the flexible member 141 in various ways, such as by bonding, crimping, screwing, and the like.

In the process that the vortex ring generator moves back and forth along the axial direction of the air duct 120, disturbance is generated on the gas in the air duct 120, so that the gas blown out from the air supply outlet 131 forms a vortex ring, and vortex air supply is realized.

Wherein the vortex ring generating part 140 includes a vortex ring generating member, and the vortex ring generating member can periodically drive airflow to be blown out through the blowing port 131; the driving device 150 includes a motor 151, a crank 152 and a connecting rod 154, the motor 151 is mounted on the housing 110, one end of the crank 152 is connected to a motor shaft of the motor 151, the other end of the crank 152 is movably connected to one end of the connecting rod 154, and the other end of the connecting rod 154 is movably connected to the vortex ring generator; thus, the motor 151 drives the connecting rod 154 to move back and forth along the axial direction of the air duct 120 by driving the crank 152 to rotate, and further drives the vortex ring generator to move back and forth, so as to periodically drive the air flow to be blown out from the air supply opening 131, so that the air blown out from the air supply opening 131 forms a vortex ring, and vortex air supply is realized.

The structure of the flexible member 141 is not particularly limited. For example, in an embodiment, when the flexible member 141 is in a natural state, the flexible member 141 is disposed in a ring shape, and the push plate 144 is installed in an inner hole of the flexible member 141 and connected to an inner edge of the flexible member 141. Specifically, the push plate 144 is connected with the inner edge of the flexible member 141 in a sealing manner, and the deformable performance of the flexible member 141 is utilized to enable the push plate 144 to move back and forth under the condition of ensuring the sealing performance, so that the gas in the wind cylinder 120 can be periodically squeezed to generate the vortex ring airflow; and simultaneously, the noise can be reduced.

Referring to fig. 5, 6 and 7, in another embodiment, when the flexible element 141 is in a natural state, the flexible element 141 is disposed in a cylindrical shape and has a first end 142 and a second end 143 opposite to each other, the push plate 144 is mounted at the first end 142, the second end 143 is connected to the housing 110 and is disposed in an open configuration, and the flexible element 141 is disposed in a gradually expanding manner from the first end 142 to the second end 143.

In this embodiment, the first and second mounting rings 160, 161 may be made of hard materials such as hard plastics and hard rubbers.

In one embodiment, the cross-sectional area of the push plate 144 is greater than or equal to the air-passing area of the air-supply outlet 131.
