When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used in this specification, the terms "upper," "lower," "inner," "outer," "bottom," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1:

The fan shaft 1 is connected with a generator 3 which can generate a trigger voltage signal.
When the flowing gas passes through the special three-impeller design of the pressure sensing unit 100 as indicated by the arrow, the pressure difference of the flowing gas causes the blades 2 to rotate. The generator 3 designed by the special three-impeller model can generate induced electromotive force due to the rotation of the blades 2, thereby generating a trigger voltage signal. The trigger voltage signal is sent to the trigger signal processing unit 200 or the control unit 300, which will be described later, to realize intelligent upgrade.
As shown in fig. 2:
the wind-based pneumatic device 400 of the present invention is composed of a pressure sensing unit 100, a trigger signal processing unit 200, and a control unit 300.
The pressure sensing unit 100 is connected with the trigger signal processing unit 200, the trigger signal processing unit 200 is connected with the control unit 300, and the pressure sensing unit 100 is connected with the control unit 300.
The trigger signal processing unit 200 and the control unit 300 may be a single chip microcomputer, and may be used by setting parameters according to the prior art.
The pneumatic device 400 is installed at the air outlet 4.
The pneumatic device 400 may be installed at any ventilation place or place where air flows in a space, such as a vehicle-mounted or household air conditioner, a fan, a ventilation duct, etc., through the change of the air flow, the pressure sensing unit 100 may sense the pressure difference, and when the change meets the requirement of a specific application, the control unit 300 may issue a control command.
As shown in fig. 3:
the pneumatic device 400 is installed at the position of the air outlet 4, and a windward part of the PCB 5 installed in the air outlet 4 needs a two-side through design, so that the flowing gas smoothly passes through the pressure sensing unit 100 to realize generation of the trigger voltage signal.
The patent proposes a method for a system for controlling a flowing gas, in order to implement more diverse intelligent applications.
As shown in fig. 4:
