Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the preferred embodiments, but the scope of the present invention is not limited to the specific embodiments described below.

It should be particularly noted that when an element is referred to as being "fixed to, connected to or communicated with" another element, it can be directly fixed to, connected to or communicated with the other element or indirectly fixed to, connected to or communicated with the other element through other intermediate connecting components.

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.

As shown in fig. 1 to 2, the present embodiment discloses a meat roaster, which is formed by connecting a plurality of heating tubes, wherein the heating tubes include an electrical heating tube 2 and a stainless steel tube 1, the electrical heating tube 2 is cylindrical, the stainless steel tube 1 is hollow and rectangular, the stainless steel tube 1 is sleeved outside the electrical heating tube 2, and the electrical heating tube 2 is disposed in the stainless steel tube 1, so as to prevent the electrical heating tube 2 from contacting with the outside and from being oxidized. Stainless steel pipe 1's both ends are uncovered, the both ends of electrothermal tube 2 are fixed in uncovered department through sealed fixed subassembly, it has the magnesium powder to fill between the outer wall of electrothermal tube 2 and stainless steel pipe 1's the inside, the inside packing of electrothermal tube 2 has magnesium oxide powder 3, the inside magnesium powder of filling of stainless steel pipe 1, can convey heat to stainless steel pipe 1 surface well, the magnesium oxide powder 3 of electrothermal tube 2 inside packing, good insulating nature and heat conductivity have, can give electrothermal tube 2 with the heat quick conduction that heater 4 sent, also can play limiting displacement to electrothermal tube 2 inside.
