Title:
DRIVING ASSEMBLY FOR VENTILATION VALVE BLADES
Document Type and Number:
WIPO Patent Application WO/2023/000669
Kind Code:
A1
Abstract:
A driving assembly for ventilation valve blades (20). A plurality of ventilation valve blades (20) are provided in an inner cavity (11) of a ventilation valve (1), the plurality of ventilation valve blades (20) are arranged circumferentially around a central line (O) of the inner cavity (11), and the central line (O) extends in a first direction (Z). The driving assembly comprises a driving device (40) and a transmission mechanism (30). The transmission mechanism (30) comprises: a first-stage transmission part, wherein the first-stage transmission part is annular, is used for being sleeved on an outer surface of the ventilation valve (1), and is connected to the driving device (40); and a plurality of second-stage transmission parts corresponding to the plurality of ventilation valve blades (20) on a one-to-one basis, wherein each second-stage transmission part is connected to a rotating shaft of the corresponding ventilation valve blade (20) and is connected to the first-stage transmission part, and the rotating shaft of each ventilation valve blade (20) is perpendicular to the central line (O). The driving device (40) is used for driving the first-stage transmission part to rotate forward or backward in a circumferential direction to synchronously drive each second-stage transmission part, such that each second-stage transmission part drives the corresponding ventilation valve blade (20) to rotate forward or backward around its own rotating shaft. By means of an external transmission structure, the problem of asynchronous rotation of the plurality of ventilation valve blades (20) can be solved.
