The invention relates to a parallel bipolar ejector with a one-way valve structure. The ejector comprises two ejector units which are arranged in parallel, wherein each ejector unit comprises an ejector body; the ejection nozzle is mounted in the inner cavity of the ejector body; the one-way valve structure comprises a backflow base connected to the ejector body and a valve diaphragm arranged in an inner cavity of the backflow base; the valve diaphragm can be jacked open by gas introduced into the inner cavity of the ejector body from the backflow base, so that the inner cavity of the ejector body is communicated with the inner cavity of the backflow base; when the pressure of gas in the inner cavity of the ejector body is larger than the pressure of the inner cavity of the backflow base, communication between the inner cavity of the ejector body and the inner cavity of the backflow base can be blocked through the valve diaphragm. By adding the one-way valve at the backflow inlet, the main flow can be prevent
