When ornamental fish is raised, the water temperature control of the aquarium is an important subject for well raising the fish, the temperature of the aquarium is kept by a heater at present, the water temperature of the aquarium is not too low, the water temperature is particularly important in winter, although most of fish do not die due to too low water temperature, the improper water temperature can affect the body color and appetite of the fish.
One of the conventional warmers is a warmer provided with a temperature control box, or called a separate warmer, which has a structure in which a warming rod and a temperature control box are assembled, and the temperature control box mainly uses a water temperature control sensing device or a water temperature control circuit to sense the water temperature, so as to control the water temperature of the aquarium to keep constant, thereby preventing the water temperature of the aquarium from being too low or too high.
However, the above-mentioned separate heater is not additionally provided with a second protection mechanism capable of responding to the over-high water temperature, so when the failure of the water temperature control sensing device (such as thermistor) or the water temperature control circuit occurs, the original temperature control protection measure will be completely out of order, the situation of over-high waste heat of the aquarium heater often occurs, or the situation of improper water temperature control occurs, for example, the water level of the aquarium decreases due to evaporation, if the water is not added, the situation of breakage of the heated glass tube heater often occurs, which leads to illness or death of fish in the aquarium, and this is a disadvantage that the conventional heater needs to be improved.
In addition, since the water temperature control sensing device is usually disposed in the warming rod, in one embodiment of the present invention, the over-temperature protection temperature sensing device can be placed in the warming rod together, and since the water temperature sensing device is already wrapped in the warming rod, only the water area around the warming rod can be sensed, and the control can be performed only according to the water temperature around the warming rod.
Therefore, if the over-temperature protection temperature sensing device (the second protection mechanism) can be independently and externally connected by the heating rod, the heating rod is configured at one end of the aquarium, and the independently and externally connected over-temperature protection temperature sensing device can be configured at any position of the other end in the aquarium, so that the water temperatures at different positions can be accurately measured, and the over-temperature protection temperature sensing device can be effectively controlled to avoid the over-high water temperature.
