Abstract
A heating pipe of automatic compensation power with a concave tooth flange comprises a heating pipe of the automatic compensation power and a flange used for fixing. The flange used for fixing is a square block whose four corners are invertedly provided with circular angles. Screw fixing holes are arranged close to the four circular angles. The flange used for fixing is provided with a concave-tooth inner ring used for connection. An outer side of the heating pipe of the automatic compensation power is provided with a surface which is cooperated with the concave-tooth inner ring on the flange used for fixing. The flange used for fixing is pasted on a surface which is cooperated with the outer side of the heating pipe of the automatic compensation power through a colloid. By using the above design, the heating pipe of the automatic compensation power with the concave tooth flange can be started through relatively low power so that the service life of the heating pipe is prolonged; usage is convenient and cost is saved; because of a semicircle concave tooth in a flange plate, a contact area between the flange plate and an epoxy resin colloid is greatly increased; an adhesive force is increased too; bonding is firm and reliable and it is not easy to fall off.
Description
Technical field
The utility model relates to heating tube, is specifically related to a kind of heating tube with recessed tooth flange auto-compensating power.
Background technology
What generally use now is single power heating pipe, only has a kind of constant power heating.But the normal temperature water temperature of zones of different or Various Seasonal is all different, want the comfortable leaving water temperature that reaches same to carry out regulating power by regulation voltage, so increase cost and efficiency not high.Even special two power suitching type heat-generating pipes also have its defect.Because ceramic heater is thermistor heater, electrical resistance temperature becomes large and becomes high-power and diminish thereupon, more powerful during than steady operation of the power while startup in other words.Especially in Instant heating type product, required stable state heating power is generally all very large, and relative starting power is larger.Too large starting power life-span of heating tube is produced to harmful effect and the whole circuit burden that is attached thereto too large, general home circuit easily occurs that momentary overload causes the phenomenons such as tripping operation.Therefore although be also to have this defect with single energetic start up work when heating but work due to two power suitching type heat-generating pipe power switched.In addition, between the smooth and ceramic heating tube of general heating pipe flange inner ring, be connected insecurely by colloid, be under pressure and easily cause heat-generating pipe to depart from.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of heating tube with recessed tooth flange auto-compensating power.
The utility model is achieved through the following technical solutions:
A kind of heating tube with recessed tooth flange auto-compensating power, comprise the heating tube of auto-compensating power and in order to fixing flange, described is four jiaos of square blocks that are respectively rounded down in order to fixing flange, and be respectively equipped with screw fixing hole near four fillet places, be provided with the concave dentate shape inner ring in order to connect in order to fixing flange; The heating tube outside of described auto-compensating power is provided with the surface of matching with the concave dentate shape inner ring on flange in order to fixing; Be bonded in by colloid in order to fixing flange outside the heating tube of auto-compensating power on surface with matching.
Further, comprise main heating power circuit and auxiliary compensation power circuit in the heating tube of described auto-compensating power, described auxiliary compensation power circuit is provided with temperature-sensitive control switch.
Adopt after technique scheme, the beneficial effects of the utility model are: 1, can open with a relatively low power, and can not cause too large burden to circuit, extend the useful life of heating tube; 2, can need to select open or do not open auxiliary heating according to the water temperature of different regions or Various Seasonal, easy to use, cost-saving; 3, the recessed tooth of ring flange interior semi-circular has increased the contact area between ring flange and epoxy resin colloid greatly, thereby has increased the power that is connected between ring flange and ceramic heating bar, bonding solid and reliable difficult drop-off.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
embodiment: a kind of heating tube with recessed tooth flange auto-compensating power, as shown in the figure, comprise the heating tube of auto-compensating power and in order to fixing flange 5, described is four jiaos of square blocks that are respectively rounded down in order to fixing flange 5, and be respectively equipped with screw fixing hole 53(in order to heating tube is fixed on other article near four fillet places), be provided with the concave dentate shape inner ring 52 of the heating tube that connects auto-compensating power in order to fixing flange 5; The heating tube outside of described auto-compensating power is provided with the surface of matching with the concave dentate shape inner ring 52 on flange 5 in order to fixing; Be bonded in by colloid (described colloid is epoxy resin colloid) in order to fixing flange 5 outside the heating tube of auto-compensating power on surface with matching.Between the smooth and ceramic heating tube of general heating pipe flange inner ring, be connected insecurely by colloid, be under pressure and easily cause heat-generating pipe to depart from.And the recessed tooth of the ring flange inside of concave dentate shape inner ring has increased the contact area between ring flange and epoxy resin colloid greatly, thereby the power that is connected between ring flange and ceramic heating bar, difficult drop-off are increased.In the heating tube of auto-compensating power, comprise main heating power circuit 22 and auxiliary compensation power circuit 23, described auxiliary compensation power circuit 23 is provided with temperature-sensitive control switch 7, when main heating power circuit 22 cannot reach while needing temperature, temperature-sensitive control switch 7 can be automatically closed, start auxiliary compensation power circuit 23, main heating power resistance 42 and the common heating of auxiliary compensation power heating resistor 41 heat to reach ideal temperature.Auxiliary compensation power circuit 23 also can carry out Artificial Control by outside connected switch as required.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
