Abstract

The invention discloses an oxygen mixing valve and a breathing machine with the same. The oxygen mixing valve comprises a body, a first adjusting part, a second adjusting part, a linear bearing and an adjusting shaft. An air channel, an oxygen channel and a mixed gas channel are formed in the body, and the mixed gas channel is communicated with the air channel and the oxygen channel. The first adjusting part is used for connecting or disconnecting the air channel and movably arranged in the air channel. The second adjusting part is used for connecting or disconnecting the oxygen channel and movably arranged in the oxygen channel. The first adjusting part and the second adjusting part are in linkage. The linear bearing is arranged in the body. The adjusting shaft is arranged in the linear bearing in a matching mode, and one end of the adjusting shaft extends out of the linear bearing to make contact with one of the first adjusting part and the second adjusting part to conveniently drive the first adjusting part and the second adjusting part to move. The oxygen mixing valve has the advantages of being high in adjusting accuracy, long in service life and the like.
