Abstract

A trash receptacle comprising a trash bag fitting device and a trash bag detection device is disclosed. The trash bag fitting device includes a vacuum assembly having air inlet and outlet respectively communicating with the inside and outside of a main body of the trash receptacle, and a motor. The trash bag detection device includes a transmitter and a receiver for respectively transmitting and receiving a signal, and a control mechanism communicatively coupled to the transmitter, the receiver and the trash bag fitting device. The control mechanism controls the trash bag fitting device according to the signal received by the receiver. The signal is a direct signal. When a trash bag is provided between the receiver and the transmitter, the receiver produces a first sense signal according to which the control mechanism stops the trash bag fitting device. Trash receptacle where the signal is a reflected signal is also disclosed.

Abstract

A trash receptacle including a bagging mechanism, which includes first and second pressing bars and a driving device, provided within a body of the trash receptacle is disclosed. First and second fixed edges intersecting at an intersection are provided at the top of internal surfaces of the body. The first pressing bar is configured to slide along the second fixed edge to gather an open end of the trash bag onto the first fixed edge. The second pressing bar is configured to slide along the first fixed edge to gather the open end of the trash bag onto the second fixed edge. The first and second pressing bars are configured to gather the trash bag to the intersection. A heat fusing device configured to heat-fuse and seal the trash bag is provided close to the intersection. The driving device configured to drive the first and second pressing bars to move.

Abstract

A trash bag detection device of an intelligent trash can, an intelligent trash can provided with the trash bag detection device, and an automatic bag changing control method. The trash bag detection device comprises a transmitting end (13) for transmitting a signal and a receiving end (14) for receiving the signal; the transmitting end (13) and the receiving end (14) are both disposed on the inner wall of the trash can; the signal received by the receiving end (14) is a direct signal transmitted by the transmitting end (13), or is a reflected signal subsequent to being transmitted by the transmitting end (13).

Abstract

Disclosed are a hot-melt device for an intelligent trash can, an intelligent trash can and a hot-melt temperature control method. The hot-melt device comprises: a heating wire (44) for fusing and heat sealing a mouth of a trash bag, the heating wire (44) being connected to a hot-melt circuit; a base (41) with heat-resistant and insulating characteristics, a first end surface of the base (41) being provided with the heating wire (44); and a control mechanism communicatively connected with the hot-melt circuit and used for controlling the hot-melt circuit. By means of the arrangement, during automatic packaging by the intelligent trash can, not only can good contact between the heating wire and a trash bag be ensured to prevent adhesion of the trash bag and improve the quality of mouth sealing, but also two functions of hot plastic packaging and hot fusing can be achieved in one step by means of the hot-melt device, thereby improving the quality and reliability of automatic packaging, reducing the control difficulty in packaging and the costs thereof, simplifying the control system and improving the stability and reliability of the system.
