AI Technical Summary

Technical Problem

The replacement process for the temperature sensor of the existing TPE hollow heating hose is complicated, requires special tools, and is prone to damaging surrounding components. In addition, the sensor is prone to aging in complex environments, which affects the measurement accuracy and response speed.

Method used

The system employs a stainless steel tube and a temperature sensor clamping and limiting mechanism. The temperature sensor can be detachably connected through a clamping plate and a sliding groove structure, simplifying the replacement process. Teflon tubing and steel wire braided mesh are used to enhance the high temperature resistance and insulation performance of the hose.

Benefits of technology

It simplifies the temperature sensor replacement process, improves replacement efficiency, reduces the risk of damage to surrounding components, and enhances sensor stability and measurement accuracy.

Abstract

The utility model discloses a TPE (thermoplastic elastomer) hollow wire heating rubber tube, which belongs to the technical field of heating rubber tubes and comprises a tube body, a stainless steel tube is fixedly mounted on the surface of the tube body, a temperature sensor is detachably mounted in the stainless steel tube, a clamping mechanism is fixedly mounted in the stainless steel tube, and the temperature sensor is detachably mounted in the stainless steel tube. A limiting mechanism is fixedly installed on the surface of the stainless steel pipe, the Teflon pipe is adopted as the pipe body, good flexibility and high temperature resistance are achieved, the carbonization phenomenon is reduced, four layers of steel wire woven meshes are adopted for the outer layer of the Teflon pipe, the working pressure of the rubber pipe is guaranteed, and four layers of heat preservation and insulation cotton are adopted for the outer layer of the steel wire woven meshes, so that the service life of the rubber pipe is prolonged. The stainless steel pipe and the temperature sensor are connected through the clamping mechanism, the clamping plate only needs to be moved out of the clamping groove during replacement, the sealing performance is not affected, the limiting mechanism is arranged, the clamping plate is limited through the limiting mechanism, and the temperature sensor can work for a long time.
