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.

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

The present invention discloses a trash bag detection device for a smart trash receptacle, comprising a transmitter for transmitting a signal and a receiver for receiving a signal, both the transmitter and the receiver being disposed on internal surfaces of the trash receptacle, wherein the signal received by the receiver is a direct signal transmitted from the transmitter or a signal from the transmitter that has been reflected. The present invention also discloses a smart trash receptacle incorporating such a trash bag detection device and a method for control of automatic bag replacement. With the present invention, the position of a trash bag in the trash receptacle can be automatically detected, allowing improved intelligent control of the trash receptacle. This is helpful in protecting the trash bag, saving resources, reducing potential safety risks of the smart trash receptacle and increasing its stability and reliability.

Trash bag detection device, smart trash receptacle and method for control of automatic bag replacement

The present invention discloses a trash bag assembly, a trash bag fitting device and a smart trash receptacle. The trash bag assembly includes a storage body and a lid. The storage body defines a first opening and an annular trough extending externally around the first opening and configured to receive a trash bag. The lid defines a second opening corresponding to the first opening and is configured to cover an open end of the annular trough so as to form, together with one side wall of the annular trough, a gap serving as a bag exit. The trash bag fitting device is configured to fit a trash bag into a main body of a trash receptacle and includes a vacuum assembly and a motor for driving the vacuum assembly. The vacuum assembly includes an air inlet and an air outlet. The air inlet communicates with an air vent in an inner wall of the main body, with the air outlet in communication with the outside of the main body of the trash receptacle. A combination of the trash bag assembly and the trash bag fitting device enables fully-automatic trash bag fitting and bagging, an increased degree of automation and intelligence of the trash receptacle, low cost and higher replacement efficiency.

Trash bag assembly for smart trash receptacle, trash bag fitting device and smart trash receptacle

The present invention discloses a bagging mechanism for trash bags and a smart trash receptacle. The bagging mechanism is disposed within a body of the trash receptacle. A first fixed edge and a second fixed edge intersecting the first fixed edge are provided at tops of internal surfaces of the body of the trash receptacle. The bagging mechanism includes a first pressing bar, which is able to slide along the second fixed edge to gather the open end of the trash bag onto the first fixed edge, and a second pressing bar, which is able to slide along the first fixed edge to gather the open end of the trash bag onto the second fixed edge. The first pressing bar and the second pressing bar are further able to work together to gather the trash bag to the intersection of the first fixed edge and the second fixed edge. In the vicinity of the intersection, a heat fusing device is disposed for heat fusing and sealing the trash bag. The bagging mechanism further includes driving means for driving the first pressing bar and the second pressing bar to move. With this arrangement, the issue that conventional smart trash receptacles do not have an automatic bagging mechanism or are only capable of semi-automatic trash bagging, with insufficient bag sealing, insecure sealing and low loading capacity can be solved.
