Abstract

The utility model relates to a heating rod for an aquarium, which comprises an insulating tube, plugs, a heating element, a power supply line and a heat conduction material, wherein the plugs are arranged at both ends of the insulating tube; the power supply line is connected with the heating element; the heat conduction material is filled between the insulating tube and the heating element; and the heating element is a PTC (Positive Temperature Coefficient) thermistor. The heating rod can achieve the constant temperature under the condition without water and a fire cannot be caused due to continuous raising of the temperature of the heating element; the power can be automatically regulated to the suitable size according to the volume of the added water; and the temperature is intelligently regulated.

Description

A kind of Shui nationality are used heating rod

Technical field

The utility model relates to heating appliances, and especially the Shui nationality are used heating rod.

Background technology

As everyone knows; The heating rod of aquarium is to be used to heat the interior water of aquarium; Make water can remain on temperature constant state; Such heating rod comprises insulation tube, is located at the plug at insulation tube two ends, is located at the heater in the insulation tube, the power line that is connected with said heater, and is filled in the Heat Conduction Material between said insulation tube and the heater.The heater performance of heating rod directly influences the performance of heating rod, even can influence the fish existence in the whole aquarium, and thus, the use of heater is vital.What the traditional heating rod was continued to use is traditional heater, and this type heater can be persistently overheating in dry-fire condition, and the last resort fuse reaches cuts off the electricity supply; As long as the intensification that conduction will continue, even can cause fire; Lack the temperature intelligent regulatory function.

Summary of the invention

The utility model technical problem to be solved provides a kind of Shui nationality and uses heating rod, does not have under the situation of water also can reach constant temperature, and heater can be because of the persistently overheating fire that causes; Power can be according to the suitable size of how much being transferred to automatically of amount of water; Intelligence is regulated temperature.

For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of Shui nationality are used heating rod; Comprise insulation tube, be located at the insulation tube two ends plug, be located at the heater in the insulation tube, the power line that is connected with said heater, and be filled in the exothermic material between said insulation tube and the heater; Said heater is the PTC thermistor.Heating rod also can reach constant temperature not having under the situation of water, and heater can be because of the persistently overheating fire that causes; Power can be according to the suitable size of how much being transferred to automatically of amount of water; Intelligence is regulated temperature.

The beneficial effect that the utility model is compared with prior art brought is:

1, heating rod also can reach constant temperature not having under the situation of water, and heater can be because of the persistently overheating fire that causes;

2, power can be according to the suitable size of how much being transferred to automatically of amount of water;

3, intelligence is regulated temperature.

Fig. 2 is the utility model longitudinal cross-section view.

Embodiment

Below in conjunction with Figure of description the utility model is described further.

Like Fig. 1, shown in 2; A kind of Shui nationality are used heating rod; Comprise insulation tube 5, be located at insulation tube 5 two ends plug 2, be located at the PTC thermistor class heater 3 in the insulation tube 5, the power line 1 that is connected with said heater 3, and be filled in the Heat Conduction Material 4 between said insulation tube 5 and the heater 3.Insulation tube 5 is used to make its inner electronic devices and components and water insulation to isolate; Plug 2 is used for insulation tube 5 sealings, the electronic devices and components of protection insulation tube 5 inside; Plug 2 backs that power line 1 passes insulation tube 5 upper ends are connected with insulation tube 5 interior heaters 3, are heater 3 power supplies; The heat that Heat Conduction Material 4 is used for heater 3 is sent dispels the heat away uniformly.If the material of the heater 3 of present embodiment PTC thermistor class is the material of high molecular positive temperature coefficient, makes heating rod under dry-fire condition, keep the temperature of safety, when in heating process when not having water; The surface temperature of heating rod can sharply rise; Temperature macromolecule in the PTC in rising takes place sharply to change, and the increase that promptly resistance value can be rapid causes the rapid decline of power meeting of heating rod; Control temperature with this and continue to rise, reach the effect of constant temperature.

Claims

1. Shui nationality are used heating rod, comprise insulation tube, be located at the insulation tube two ends plug, be located at the heater in the insulation tube, the power line that is connected with said heater, and be filled in the Heat Conduction Material between said insulation tube and the heater; It is characterized in that: said heater is the PTC thermistor.
