AI Technical Summary
Currently, the connection between the oil supply pipe and the isolation device in fuel stoves is a fixed connection, which makes the oil supply prone to deformation in high and low temperature environments, resulting in damage to the connection.
An isolation device for the fuel injection pipe of a fuel stove was designed. It adopts a spring and limiting slip ring structure and is fixedly connected to the fuel supply pipe through a connecting threaded hole. By utilizing the deformation of the spring and the guidance of the limiting slip ring, the inner oil inlet pipe is allowed to move accordingly according to the change of the fuel supply pipe length, preventing violent deformation and pulling at the connection.
It effectively prevents damage to the connection between the oil pipeline and the isolation device caused by severe deformation and pulling, and improves the stability and durability of the connection.
