Description

Technical Field

[0001] The utility model relates to the technical field of aquarium heating, in particular to a constant temperature heating device for an aquarium. Background Art

[0002] In order to provide a suitable living environment and ensure the healthy growth of aquatic organisms, the water temperature control in the aquarium is crucial. Different types of aquatic organisms have different requirements for water temperature, so it is necessary to accurately control the water temperature in the aquarium.

[0003] At present, most of the existing aquarium heating devices on the market place the temperature measuring probe in the heating rod, which results in the position of the heating rod determining the position of the temperature measuring probe. It may not fully represent the average temperature of the entire aquarium. The water beside the heating rod reaches the preset temperature, but the water temperature at a relatively far distance is still relatively low. If the temperature measuring probe has problems, it may be necessary to replace the entire heating rod, resulting in waste. Even some aquarium heating devices integrate the control circuit on the heating rod. The circuit inside the heating rod is easily affected by water vapor. Especially after long-term use, it may cause the circuit to short-circuit or be damaged. Since the circuit is integrated with the heating rod, once there is a problem, it may be more troublesome to repair, and even professional personnel may need to intervene.

[0004] The present utility model is made based on the above situation. Summary of the Utility Model

[0005] The utility model overcomes the deficiencies of the prior art and provides a constant temperature heating device for an aquarium that can more accurately control the water temperature in the aquarium and is convenient for maintenance.

[0006] The present utility model is realized through the following technical solutions:

[0007] A constant temperature heating device for an aquarium, comprising a controller. The controller is provided with a control unit capable of presetting a temperature threshold, an adjustment unit for adjusting the temperature threshold, and a display unit for displaying the temperature threshold. The controller is connected by a wire to a heating rod that can be placed in the aquarium for heating, so that after the heating rod is placed in the aquarium, the controller can be placed outside the aquarium. The controller is also connected by a wire to one or more temperature measuring probes that can be placed in the aquarium to detect the water temperature in the aquarium and then send signals to the control unit for comparison with the temperature threshold. When the temperature is lower than the temperature threshold, the control unit controls the heating rod to heat. When the temperature reaches the temperature threshold, the control unit controls the heating rod to stop heating. The heating rod is electrically connected to the control unit, and the temperature measuring probe is electrically connected to the control unit.

[0020] 3. The heating wire is sheathed with a glass tube, and the glass tube is sheathed with a titanium tube. The combination of the glass tube and the titanium tube provides two layers of protection. Even if the glass tube is damaged, the titanium tube can prevent the heating wire from directly contacting the water body, avoiding electric leakage accidents. The titanium tube has extremely high corrosion resistance and is hardly damaged even when immersed in water for a long time, extending the service life of the heating rod.

[0021] 4. The heating wire is folded in half at the head and tail, and an insulating sheet is provided between the head section and the tail section of the heating wire to separate the two sections, effectively lengthening the length of the heating wire, thereby achieving a better heating effect and making the internal structure of the heating rod more compact.
