Fig. 3 is the another kind of roasting pipe structure of prior art.As shown in Figure 3; The patent No. is to disclose a kind of carbon fiber electric heating core quartz electrothermal tube in 200720020278.0 the application; It is made up of quartzy shell 36, external electrode 31, transition brace 32, external spiral electrode 33, hollow edged electrode carriage 35 and tubulose carbon fiber electric heating core 34; External electrode 31 is connected the two ends that are arranged on quartzy shell 36 through transition brace 32 with external spiral electrode 33; Tubulose carbon fiber electric heating core 34 is located among the quartzy shell 36, is provided with hollow edged electrode carriage 35 in the middle of the two ends of tubulose carbon fiber electric heating core 34, and external spiral electrode 33 is fastened on the cylindrical at tubulose carbon fiber electric heating core 34 two ends; Be filled with inert protective gas 38 in the quartzy shell 36, the wall of quartzy shell 36 is provided with vaccum exhaust outlet 37.
Barbecue tube of the prior art is in microwave oven uses; Microwave burr frequent and carbon fiber surface is had an effect and spark phenomenon occurred; Influence the safety in utilization of product, because quartz glass tube directly contacts with outside, be easy to fragmentation simultaneously; It is bad to cause product quality, influences user's impression.
Summary of the invention
Technical problem to be solved by this invention is the shortcoming that overcomes prior art, and a kind of roasting pipe structure that can effectively strengthen described barbecue tube intensity and can avoid itself and microwave to interfere is provided.
The technical scheme that the present invention adopted is:
A kind of barbecue tube comprises shell, external electrode and carbon fiber electric heating core, outside described quartzy shell, also is provided with the round metal barrel mast coaxially, offers through hole on the described round metal barrel mast.
Preferably, described round metal barrel mast is processed by iron or aluminium.
Be provided with at described metal barrel mast two ends and can insert the connector of its end with mating, described connector center is provided with the through hole with described external electrode coupling, and wherein said connector is processed by insulating material.And described connector comprises the end and the shaft shoulder, the diameter of the described shaft shoulder and the internal diameter of described cylindrical column coupling.
A kind of microwave oven that uses barbecue tube as claimed in claim 1.
The invention has the beneficial effects as follows: roasting pipe structure of the present invention; In the outer setting of quartz ampoule the round metal barrel mast; Simultaneously on described round metal barrel mast, offer intensive through hole, guaranteed the efficiency of heating surface when having avoided the generation of spark phenomenon, improved the fail safe in using; And strengthened the intensity of quartz ampoule, the infringement of avoiding it to cause because of external force.
