Instant pipeline heater and manufacturing method thereof

Abstract

The invention discloses an instant pipeline heater. The instant pipeline heater comprises a water pipe and a tubular heating body, the tubular heating body comprises a first conductive end, a second conductive end and a tubular heating wall, a spacing groove divides the tubular heating wall into an electrified heating circuit connected between the first conductive end and the second conductive end, and the tubular heating body sleeves the outer wall of the water pipe and is tightly attached to the outer wall of the water pipe. The heater has the advantages that incrustation is not easily caused, drinking water is sanitary, the structure is simple, and installation is simple and easy. The invention further discloses a manufacturing method for the instant pipeline heater. The manufacturing method comprises the steps that firstly, the water pipe is prepared; 2, the required spacing groove is cut out in the tubular heating wall by using laser grooving equipment, and the spacing groove processes the tubular heating wall into the electrified heating circuit connected between the first conductive end and the second conductive end so as to obtain the required tubular heating body; and 3, the outer side wall of the water pipe is tightly sleeved with the tubular heating body prepared in the step 2. The preparation method has the advantages of being simple in processing and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of an instant pipeline heater, in particular to an instant pipeline heater and a manufacturing method thereof. Background technique [0002] At present, instant water dispensers have increasingly entered families or offices. The most important part of the instant water dispenser is the instant heating tube. The traditional instant heating tube, such as the Chinese utility model patent number: 2019200951537, name: an instant heating tube and water dispenser, authorized Announcement date: November 22, 2019, it includes a heating conduit, a first insulating layer is provided outside the heating conduit, a heating body and a second insulating layer are provided outside the first insulating layer, and the second insulating layer Distributed between the heating bodies; the heating body is a spiral heating wire, the second insulating layer is a spirally coiled insulator, and the heating body and the second insulat...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned instantaneous heating tube also has the following disadvantages: (1) Since the first insulating layer is arranged on the outside of the heating tube to prevent the contact between the heating body and the heating tube from conducting, the heating tube is made of conductive metal (2) In addition, a first insulating layer is set between the outside of the heating conduit and the heating body, and the heating wire and the second insulating layer are coiled at intervals The method is set on the surface of the first insulating layer, its structure is complex, the coiling process is difficult, and the heating wire is difficult to stick to the first insulating layer, and the heat transfer effect is easily affected by the gap between the heating wire and the first insulating layer
