Some embodiments of this application provide an injection nozzle and an injection apparatus containing same. The injection nozzle includes a body, an injection pipe, and a baffle. The body contains a channel arranged along a height direction of the injection nozzle. A first outlet is disposed at a lower part of the channel. The injection pipe is threaded through the channel in a manner of reciprocating movement along the height direction. The baffle is connected to the body and configured to cover the first outlet when a lower end portion of the injection pipe is higher than the first outlet, and be propped open by the injection pipe when the lower end portion of the injection pipe is lower than the first outlet.
