Abstract

This invention discloses a portable and simple breathing trainer. The shell has multiple holes at its top and bottom. An air nozzle is located on the left side of the shell and fixedly connected to it, allowing air to be delivered to the user's mouth. A filter is installed on the inhalation training mechanism to filter impurities from the air. A cleaning brush is fixedly installed on the inhalation training mechanism to clean the filter from left to right. By rotating a rotating ring, the invention drives a second sealing plate to rotate, thus changing the opening between the first and second sealing plates. A smaller opening makes it more difficult for air to pass through, requiring greater suction. Conversely, a larger opening has the opposite effect, allowing users to easily adjust the opening size to suit their needs for training.
