Heat fusing devices, smart trash receptacle and methods for controlling heat fusing temperature

The present invention discloses a heat fusing device for a smart trash receptacle, including: a heating wire for fusion-cutting and thermally sealing an open end of a trash bag, the heating wire being connected to a heat-fusing circuit; a base having heat-resistant and insulating properties, the base having a first end surface on which the heating wire is arranged; and a control mechanism communicatively coupled to the heat-fusing circuit for control thereof. The present invention also discloses a smart trash receptacle incorporating the heat fusing device and a method for controlling a heat fusing temperature. With the present invention, during automatic bagging by the smart trash receptacle, good contact between the heating wire and the trash bag can be ensured while preventing adhesion of the trash bag. This results in improved sealing quality and enables the fulfillment of two tasks, i.e., thermoplastic sealing and thermal fusion-cutting, in the same action of the heat fusing device. As a result, higher automatic bagging quality and reliability are obtainable at lower bagging control difficulty and reduced bagging cost. Moreover, control in the system is simplified, and the stability and reliability of the system are increased.
