Flow guide reinforcement pipe for coffee machine

Abstract

The invention relates to the field of flow guide pipe equipment for a coffee machine, in particular to a high-temperature resistance and high-pressure resistance flow guide reinforcement pipe for the coffee machine. The high-temperature resistance and high-pressure resistance flow guide reinforcement pipe comprises a Teflon water pipe and a connecting piece, wherein the Teflon water pipe is of a single-layer or multilayer structure; the connecting piece is of a single-layer or multilayer structure; each layer of the connecting piece is made of a high-temperature resistance material or a modified high-temperature resistance material; at least one layer of the connecting piece is made of the high-temperature resistance material and other layers of the connecting piece are made of the modified high-temperature resistance materials; the connecting piece is connected and fixed with the Teflon water pipe in an adhering, welding or hot-pressing baking manner; the connecting piece is formed and fixed on the Teflon water pipe in a die molding, injection molding or soaking molding manner. The high-temperature resistance and high-pressure resistance flow guide reinforcement pipe for the coffee machine has a simple structure and adopts a simple machining process; a metal inner and outer rivet sleeve punching process does not need to be carried out; an inner flow passage of a flow guide pipe is smooth; when the high-temperature resistance and high-pressure resistance flow guide reinforcement pipe works, the fluid pressure is stable, working stability is high and cost is saved.

Description

Technical field: [0001] The invention relates to the field of diversion tube equipment for coffee machines, in particular to a high-temperature and high-pressure resistant diversion enhancement tube for coffee machines. Background technique: [0002] At present, the development of coffee machines is getting faster and faster, and there are more and more types. People have higher and higher requirements for coffee machines, and higher temperature and pressure resistance requirements are also put forward for related parts of coffee machines that are in contact with high temperature and high pressure. In particular, if the structure of the heat-resistant and pressure-resistant diversion tube is poor or the strength is low, it is easy to leak or store for a long time, which will lead to electrical failures such as leakage and potential safety hazards. [0003] In the prior art, the coffee machine guide tube mostly adopts single-layer Teflon (polytetrafluoroethylene) or multi-lay...

AI Technical Summary

Problems solved by technology

In particular, if the temperature-resistant and pressure-resistant diversion tube is poor in structure or low in strength, it is prone to leakage or storage after long-term work, which will lead to electrical failures such as leakage and potential safety hazards.

[0003] In the prior art, the coffee machine diversion tube mostly adopts single-layer Teflon (polytetrafluoroethylene) or multi-layer Teflon (each layer is polytetrafluoroethylene, or each layer is respectively polytetrafluoroethylene or modified Teflon). Polytetrafluoroethylene) water pipes and related installation components, the installation components are mostly aluminum or copper inner and outer rivet fixed structure, the metal inner and outer rivet structure needs to be assembled by stamping process, the process is relatively Complicated, relatively low efficiency, high cost

If the process is not properly operated, it is easy to cause local damage to the Teflon water pipe

In addition, the inner and outer riveted sleeve structures lead to a sharp decrease in the inner diameter at both ends of the diversion tube, and the fluid pressure suddenly increases at the outlet of the diversion tube, which may easily cause accidents such as pipe burst and leakage.
