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, a driving device 160 and a reset element 170. 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. The vortex ring generator 140 is installed in the housing 110, the vortex ring generator 140 includes a vortex ring generator capable of periodically driving airflow to be blown out through the air supply opening 131, the vortex ring generator is provided with a pull rod 150 extending along the axial direction of the air duct 120, and the pull rod 150 is laterally provided with a contact portion 151 in a protruding manner. The driving device 160 includes a motor 161 and a crank 162, one end of the crank 162 is connected to a motor shaft of the motor 161, and the motor 161 is configured to drive the crank 162 to rotate, so that a free end of the crank 162 periodically abuts against the abutting portion 151 (as shown in fig. 7), thereby driving the pull rod 150 to move in a direction away from the air supply opening 131. The reset member 170 is configured to drive the pull rod 150 to move toward the air supply opening 131 when the free end of the crank 162 is separated from the abutting portion 151 (as shown in fig. 8).

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.
