The specific structure of the breathing apparatus will be mainly described below.

Referring to fig. 1-9, in an embodiment of the present utility model, the breathing apparatus includes a ventilator 100 and a ventilation circuit 200. The ventilator 100 has an air outlet slot 110; the vent line 200 includes an air inlet fitting 210, the air inlet fitting 210 having an air inlet cavity 211, at least a portion of the air inlet fitting 210 being insertable into the air outlet groove 110 such that the air inlet cavity 211 communicates with the air outlet groove 110; one of the ventilator 100 and the air inlet connector 210 is provided with an electrical connector 212, the other one is provided with an electrical connector 120, the electrical connector 212 and the electrical connector 120 can be in fit connection, the connection direction of the electrical connector 212 and the electrical connector 120 is the same as the connection direction of the air inlet connector 210 and the air outlet groove 110, so that when the air inlet connector 210 is inserted into the air outlet groove 110, the electrical connector 212 can be connected with the electrical connector 120 in a connection mode.

In this embodiment, the ventilator 100 may be provided with an electrical interface 120, and the air inlet connector 210 is provided with an electrical connector 212; the breathing apparatus may also be provided with an electrical connector 212, and the air inlet connector 210 is provided with an electrical connector 120, which is not particularly limited herein. Taking the ventilator 100 with the electrical interface 120 and the air inlet connector 210 with the electrical connector 212 as an example, the electrical connector 212 is just plugged into the electrical interface 120 when the air inlet connector 210 is plugged into the air outlet groove 110 by reasonably setting the position relationship between the electrical interface 120 and the air outlet groove 110 and the position relationship between the electrical connector 212 and the air inlet connector 210, so as to realize the electrical conduction between the electrical connector 212 and the ventilator 100, so that the ventilator 100 can supply power to the heating wires. In this way, the user is operating to connect the air inlet connector 210 to the air outlet groove 110, so that the air flowing out from the respirator 100 can flow to the air inlet cavity 211 to be conveyed to the respirator through the ventilation pipeline 200, and meanwhile, the work of communicating the electrical connector 212 with the electrical connector 120 is also completed, so that the electrical connector 212 is not required to be communicated with the electrical connector 120 by additional operation, the operation procedure is omitted, and the use convenience of the breathing equipment is improved.

Because the clamping protrusion 214 is clamped on the hole edge of the clamping hole 112, the axial movement of the air inlet connector 210 in the air outlet groove 110 is limited, the air inlet connector 210 is ensured to be inserted into the air outlet groove 110 at a preset depth and not to be easily separated from the air outlet groove 110, and the installation stability of the air inlet connector 210 is improved.

Further, the locking protrusion 214 is disposed on a side of the locking member 213 away from the sidewall of the air outlet groove 110, and is located at an end of the locking member 213 away from the air inlet connector 210, the locking protrusion 214 has a top and a bottom, and the bottom is disposed near the air inlet connector 210; the top portion has an introduction slope 215, and the introduction slope 215 extends from the top portion to the bottom portion of the catching protrusion 214 in a direction in which the sidewall of the gas outlet groove 110 extends toward the middle portion of the gas outlet groove 110.
