An intelligent heating rod and an aquarium. The Intelligent heating rod (1) comprises: a heating core (101), a temperature control unit (102), a thyristor (103) and a power line (104), wherein two output ends of the thyristor (103) are respectively connected to the heating core (101) and the power line (104), and an input end thereof is connected to the temperature control unit (102); the temperature control unit (102) performs zero-crossing detection on an alternating current provided by the power line (104), controls the ON and OFF of the thyristor (103) when the alternating current is at zero crossing point, and adjusts a time scale of heat generation and non-heat generation of the heating core in unit time by controlling a time scale of the thyristor (103) in an ON state and in an OFF state in unit time, and thus adjusts the heating power of the intelligent heating rod (1). The present intelligent heating rod (1) uses a thyristor (103) to control the power on/off of a heat generation core (101), so that the oxidation and adhesion phenomena can be prevented from occurring to a mechanical contact, and by using the policy of triggering a thyristor at a zero-crossing point so as to enable same to work in a complete alternating current period, the service life of the thyristor (103) is improved, and a temperature control function with higher accuracy can be realized, which is more beneficial for the healthy growth of fishes. |
