Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature steam heating, in particular to a high-temperature steam heating pipe. Background Art

[0002] As people's living standards and quality of life improve, residents' living conditions continue to improve, and they have higher requirements for the quality of living environment. As a result, high-end steamers and steam floor washers have emerged in the industrial and all home appliance fields. The working principle of a steam floor washer is to use steam cleaning, also known as supersaturated steam cleaning. It uses saturated steam under high temperature and high pressure to dissolve the oil particles on the surface to be cleaned and vaporize them, which can make the surface cleaned by saturated steam reach an ultra-clean state. At the same time, supersaturated steam can effectively cut into any tiny holes and cracks, peel off and remove the stains and residues in them, and then clean the stains by rotating the floor washing disc.

[0003] However, existing steam generating devices have the following problems: (1) the steam generating device is large in size, which is not conducive to miniaturization design; (2) the steam generating device has low steam generation efficiency and a long waiting time for steam generation.

[0004] Based on this, the applicant proposed a miniature high-efficiency steam generating device and a floor scrubber (announcement number: CN219036587 U), including a heating body and a shell. The heating body is a rod-shaped structure, and the shell is a barrel-shaped sealed structure. The heating body is coaxially arranged in the shell, and the inner diameter of the shell does not exceed twice the outer diameter of the heating body; the heating body includes a magnesium oxide core rod, a resistance wire and a metal protective sleeve, the resistance wire is wound around the outside of the magnesium oxide core rod, and the metal protective sleeve is sleeved on the outside of the resistance wire; one end of the magnesium oxide core rod is provided with a temperature measuring cavity extending inward, and the other end is provided with two wiring cavities extending inward, and the temperature measuring cavity and the wiring cavity are connected; the temperature measuring cavity is used to install a temperature sensor, and the wiring cavity is used to pass the temperature sensing line, and the temperature sensing line and the temperature sensor are connected.

[0005] It was found in actual use that the steam generating device made by adopting the above scheme still had the problem of being too large in size as the water was heated outside the heating body.

[0006] Therefore, in view of the shortcomings of the prior art, it is necessary to design a high-temperature steam heating pipe to solve the above problems. Utility Model Content

[0007] In order to overcome the above-mentioned deficiencies in the prior art, the utility model aims to provide a high-temperature steam heating pipe.

[0008] To achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is: a high-temperature steam heating tube, comprising: an inner tube, an outer tube, an insulating tube and a heating wire, the insulating tube is sleeved on the outer periphery of the inner tube, the outer tube is sleeved on the outer periphery of the insulating tube, an annular cavity is formed between the outer tube and the insulating tube, the heating wire is constituted as a spring-like structure and is sleeved in the annular cavity, the annular cavity is filled with magnesium oxide powder and sealing end covers are provided at both ends.

[0009] The preferred technical solution is: a through hole is provided in the wall of the insulating tube, and an alloy resistance wire is passed through the through hole.

[0010] The preferred technical solution is that the insulating tube is a magnesium oxide tube.

[0011] The preferred technical solution is that the heating wire is an alloy heating wire.

[0012] The preferred technical solution is that both the inner tube and the outer tube are made of stainless steel tubes.

[0013] A preferred technical solution is: the outer diameter of the inner tube matches the inner diameter of the insulating tube, and the inner diameter of the outer tube is larger than the outer diameter of the insulating tube.

[0014] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0015] The utility model provides a high-temperature steam heating tube, whose inner tube is used as a water flow channel, that is, the inner ring of the spring-shaped heating wire is used to heat the water flow. Compared with the background technology that uses the outer ring of the spring-shaped heating wire to heat the water flow, it has a smaller volume; and, under the condition that the spring-shaped heating wire structure is the same, in this solution, the amount of water heated by the inner ring is much less than the amount of water heated by the outer ring in the background technology. Under the condition of the same heating power, the steam generation efficiency of this solution will be further improved. BRIEF DESCRIPTION OF THE DRAWINGS
