A sealing device includes a frame member having an opening portion, an engaging portion with which a first portion of the bag-shaped film body is engaged, and a heater unit; a moving member having an attaching portion to which a second portion of the bag-shaped film body is attached and a heater receiving portion; and a handle member that is slidably inserted in the frame member and coupled to the moving member. The moving member is arranged so as to be movable in the opening portion toward the engaging portion, and the heater unit and the heater receiving portion are configured to clamp the bag-shaped film body and heat and seal it in a state in which the moving member is moved to the vicinity of the engaging portion by the handle member.

An autonomous toilet may include a waste receptacle having a receptacle opening, a seat extending at least partially around the receptacle opening, the seat being configured to support a user of the autonomous toilet, a plurality of driven wheels configured to urge the autonomous toilet across a surface, one or more sensors configured to sense one or more conditions of a surrounding environment, and a controller communicatively coupled to the one or more sensors and the plurality of driven wheels.

An automatic packaging mechanism includes a melting assembly having a heating structure, a gathering assembly, and a buffer. The gathering assembly includes a gathering base and a pressing base. A passage is formed between the pressing base and the heating structure. The gathering base is driven by a drive member to move toward or away from the heating structure. The buffer is slidably sleeved over an outer periphery of the melting base. When the drive member drives the gathering base to move toward the heating structure, the pressing base contacts the buffer and contacts the heating structure, and an opening of a garbage bag to be heat-sealed is gathered between the pressing base and the heating structure by the gathering base. Upper and lower parts of the heating structure simultaneously seal adjacent garbage bags, and a middle part of the heating structure cuts the sealed garbage bags apart.

A camp toilet may include at least three legs each having a bracket with at least two threaded apertures for receiving at least two fasteners, each fastener positioned in a different one of the at least two threaded apertures, and a seat having a flat surface and forming (a) an internal aperture and (b) evenly positioned around the flat surface for each of the at least three legs, at least two open-ended slots each sized and shaped to receive the at least two fasteners, wherein the fasteners secure the leg to the seat when positioned within the at least two slots and tightened. The camp toilet is modular, lightweight, and easily disassembled and packed for transport.

A waterless toilet comprises: a base, a first roller, a second roller, two support brackets, two support plates, two cloth rolls having a plastic sheet respectively, a driver, a seat cushion bracket, and a toilet seat; wherein the plastic sheets of the two cloth rolls are laid on the two support plates, thus excrement from the toilet seat is captured completely; thereby human waste is collected without using water and small of collected human waste is prevented, furthermore, consumable costs of plastic sheet are saved.

A portable toilet system for outdoor use includes a plurality of pegs and a biodegradable bag liner. Each peg features a stake with a pointed end for ground insertion and a peg body with a horizontal recess to secure the bag liner. The peg body has two magnets adjacent to the recess and a removable slider with a magnet that can couple to either magnet on the peg body, allowing for adjustable bag liner securement. The biodegradable bag liner is configured to be held open by the pegs, providing a convenient and environmentally friendly solution for managing human waste during outdoor activities. The system ensures secure placement and easy adjustment of the bag liner, enhancing user convenience and environmental safety.

A plastic bag packaging and separating device for an intelligent packaging toilet includes a synchronous belt, a driving shaft, a motor, guide rods, a gathering mechanism, roller assemblies, a hot melting base, and a hot melting device, and further includes a silica gel strip container, an exhaust sheet, and a lower rotating mechanism. The motor is connected to the driving shaft. The synchronous belt is wound around the driving shaft. The gathering mechanism is engaged with the synchronous belt through an engaging member and is slidably arranged on the guide rods. The hot melting device is mounted on the hot melting base. The lower rotating mechanism is connected to the hot melting base. The roller assemblies are respectively arranged below the guide rods. The silica gel strip container is arranged on the gathering mechanism. The exhaust sheet is arranged below the silica gel strip container.

A sealing device includes a frame member having an opening portion, an engaging portion with which a first portion of the bag-shaped film body is engaged, and a heater unit; a moving member having an attaching portion to which a second portion of the bag-shaped film body is attached and a heater receiving portion; and a handle member that is slidably inserted in the frame member and coupled to the moving member. The moving member is arranged so as to be movable in the opening portion toward the engaging portion, and the heater unit and the heater receiving portion are configured to clamp the bag-shaped film body and heat and seal it in a state in which the moving member is moved to the vicinity of the engaging portion by the handle member.
