Detailed Description

For a more clear and complete description of the technical solution of the present invention, the following description is made with reference to the accompanying drawings.

Referring to fig. 1-3, the present invention provides a heating respiratory tube, which comprises a tube body 1, a heating wire 2, a sleeve 3 and a condensation-blocking isolation tube 4; the heating wire 2 is contained in the sleeve 3, the sleeve 3 and the coagulation-resistant isolating pipe 4 are wound on the outer wall of the pipe body 1, and the sleeve 3 and the coagulation-resistant isolating pipe 4 are arranged at intervals.

Because the heating wire 2 in the sleeve 3 is heated, and the pipe body 1 is wrapped by the condensation-resistant isolating pipe 4 and the sleeve 3, the condensation-resistant isolating pipe 4 and the sleeve 3 prevent the influence of the external room temperature on the pipe body 1, so that the airflow is influenced by the external environment as little as possible when flowing through the pipe body 1.

Referring to fig. 1 and 2, the sleeve 3 is spirally wound from one end to the other end of the pipe body 1, and is uniformly wound along the outer wall of the pipe body 1; the anti-coagulation isolation pipe 4 is spirally wound from one end to the other end of the pipe body 1, and is uniformly wound along the outer wall of the pipe body 1, and the anti-coagulation isolation pipe 4 and the sleeve 3 are arranged at intervals.

Referring to fig. 1, the heating breathing tube further includes a plurality of heating joints 5 and a power supply joint 6, the tube body 1 is communicated with the heating joints 5, and the power supply joint 6 is fixedly installed on a side surface of the heating joints 5.
