Abstract
The utility model discloses a porcelain heating bar capable of raising temperature fast and particularly relates to an improved structure of a resistor heating line, belonging to H05B3 category in IPC (international patent classification). The porcelain heating bar consists of a ceramic cylindrical core body and a tubular ceramic layer, wherein the tubular ceramic layer is formed in a way that ceramic plates are curled and are tightly sleeved outside the ceramic cylindrical core body, a resistor heating line is printed on the inner lateral wall of the tubular ceramic layer, the two tail ends of the heating line respectively pass through two small holes in the inner lateral wall and are connected with two rectangular electrode welding pads on the outer lateral wall, and leads are respectively welded on the electrode welding pads. The improvement lies in that the heating line adopts an unequal width design along the length direction of a bar body, and the line width close to the two tail ends of the heating line is gradually reduced from the top end to the low end. The ceramic heating bar provided by the utility model raises temperature faster.
Description
Technical field
The utility model relates to ceramic heater; Especially can be applicable to Automobile Detection transducer, vaporizer, electric iron, lambda sensor etc. needs the ceramic heat of heat temperature raising parts excellent; Specifically be the improvement structure to the resistance heating circuit, it is other in the IPC classification, to belong to the big category of H05B3.
Background technology
Ceramic heater is a kind of efficient hot branch uniform heating device; Can guarantee that hot-face temperature is even; The focus and the cold spot of equipment have been eliminated; And have advantages such as long-life, good heat insulating, strong, corrosion-resistant, the diamagnetic field of mechanical performance, being widely used in Automobile Detection transducer, vaporizer, electric iron, lambda sensor etc. needs in heat temperature raising parts or other occasions.
The structure of existing ceramic heat rod is: the ceramic cylinder core body reaches by the curling tubular ceramic layer that forms outside the ceramic cylinder core body that also tightly is placed in of potsherd to be formed; Tubular ceramic layer madial wall is printed with the resistance heating circuit; It is continuous with two electrode pads of lateral wall that these heating circuit two ends pass two apertures of madial wall respectively, is welded with lead-in wire on the electrode pad respectively.
The weak point of existing ceramic heat rod is: the structural design decision ceramic heat rod of existing resistance heating circuit can only be the heating system that slowly heats up, and can't be applicable to the applications that some need be rapidly heated.
The utility model content
Therefore, the utility model propose a kind of intensification that has improved the resistance heating line construction fast the ceramic heat rod to satisfy the use needs of some occasions.
The utility model is realized through following technical scheme:
A kind of intensification is the ceramic heat rod fast; Form by the ceramic cylinder core body and by the curling tubular ceramic layer that forms outside the ceramic cylinder core body that also tightly is placed in of potsherd; Tubular ceramic layer madial wall is printed with the resistance heating circuit; It is continuous with two rectangular electrode pads of lateral wall that these heating circuit two ends pass two apertures of madial wall respectively, is welded with lead-in wire on the electrode pad respectively.Improvements are: described heating circuit diminishes from the live widths of upper end to the lower end near heating circuit two ends along adopting not wide design on the barred body length direction gradually.
Further, described lower end the live width at narrow place be the 50%-80% of the live width of upper end the widest part.The live width of heating circuit upper and lower end adopts this gradual change ratio, make heating effect more fast, heating is more concentrated.
The utility model adopts as above technical scheme; Structure to the heating circuit is improved, and the heating circuit diminishes from the live widths of upper end to the lower end near heating circuit two ends along adopting not wide design on the barred body length direction gradually; Make it have bigger resistance; In the thermal treatment zone, assemble higher heat, realize being rapidly heated, go for the applications that some need be rapidly heated.

Fig. 2 is the tubular ceramic layer of ceramic heat rod and the structural representation after the expansion of ceramic cylinder core body;
Fig. 3 is existing heating line construction sketch map;
Fig. 4 is the improved heating line construction of a utility model sketch map.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Consult illustrated in figures 1 and 2; The ceramic heat rod curls and tightly is placed in the tubular ceramic layer 2 that ceramic cylinder core body 1 outside forms by ceramic cylinder core body 1 and by potsherd and forms; Tubular ceramic layer 2 madial walls are printed with resistance heating circuit 3; This heating circuit two terminal 31 passes two apertures of madial wall respectively and links to each other with two rectangular electrode pads 4 of lateral wall, is welded with lead-in wire 5 on the electrode pad 4 respectively.
Consult shown in Figure 3ly, existing heating circuit 3 is along adopting even wide design on the barred body length direction.That is, the live width near the upper end 321 ' of heating circuit two terminal 31 and lower end 322 ' is identical.
Consult shown in Figure 4ly, the heating circuit 3 of the utility model diminishes from the live width of upper end 321 to lower end 322 near heating circuit two terminal 31 along adopting not wide design on the barred body length direction gradually.Preferably, described lower end 322 the live width d2 at narrow place be the 50%-80% of the live width d1 of upper end 321 the widest part.The live width of heating circuit upper and lower end adopts this gradual change ratio, make heating effect more fast, heating is more concentrated.
The utility model improves the structure of heating circuit; The heating circuit is along adopting not wide design on the barred body length direction; From diminishing gradually near the heating circuit two terminal live widths of upper end to the lower end, make it have bigger resistance, in the thermal treatment zone, assemble higher heat; Realization is rapidly heated, and goes for the applications that some need be rapidly heated.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection range of the utility model.
