Abstract: An autonomous robotic device capable of vacuum cleaning and purifying air includes an autonomous robotic vacuum cleaner for moving autonomously and vacuum cleaning, and an air purifier. The autonomous robotic vacuum cleaner has a power supply and a top surface provided with a plurality of positioning members. The air purifier has an air inlet, an air outlet, and a plurality of matching members at the bottom thereof. The air purifier is detachably disposed on the autonomous robotic vacuum cleaner in a way that the matching members are in contact with the positioning members to create a positioning relationship for positioning the air purifier on the autonomous robotic vacuum cleaner, and an electrical connection to enable the air purifier to receive electric power from the power supply of the autonomous robotic vacuum cleaner.

Abstract: A mahjong game system using touch panel includes: a computer, and four player consoles in communication with the computer by a wired or wireless communication method. The computer includes a touch panel at the top side for displaying game pictures and a mahjong game program installed therein and providing a speech recognition process for identifying multiple specific voice commands. The four player consoles are individual touch panels having an elongated shape. Each player console defines a tiles-in-hand displaying portion and a command displaying portion. Further, a voice sensor is installed in the computer or each player console.

Abstract: A border-signal generating and wire winding device for border recognition of a self-propelled mower includes a seat; a reel rotatably installed on the seat; a lever provided at one end of the reel for a user to operate and rotate the reel; two power sockets provided on the seat or on the reel; an electric wire removably wound around the reel and having two plugs at two ends thereof for being detachably plugged into the two power sockets; and a signal-generating module provided on the seat or on the reel and electrically connected to the two power sockets. When the electric wire is connected to the two power sockets through the two plugs, the signal-generating module continuously generates a border signal that is continuously transmitted to the electric wire through the two power sockets.

Abstract: The present disclosure illustrates an mite-removing vacuum cleaner including a cleaner body and a mite-removing device. The mite-removing device is detachably combined with a front section of the cleaner body and includes a circuit board, a vibrator and a UV sterilization lamp. The circuit board is electrically connected to a power source, and the vibrator is electrically connected to the circuit board. The UV sterilization lamp is located at the bottom surface of the mite-removing device and electrically connected to the circuit board. When the cleaner body is assembled with the mite-removing device, the mite-removing vacuum cleaner can perform mite-removing and dust-sucking functions both; when the cleaner body is disassembled from the mite-removing device, the cleaner body can perform the dust-sucking function independently. Therefore, the mite-removing vacuum cleaner of the present disclosure can provide the mite-removing and dust-sucking functions both, or provide the dust-sucking function independently.

Abstract: A mobile robotistic mopping machine is formed of a body frame, a mop cloth, a power device, and a control device. The power device includes two opposite wheels and two opposite motors connected with the respective wheels for driving the wheels to rotate to further enable the body frame via the wheels to make the mop cloth move forward for cleaning the ground. The control device is electrically connected with the motors for controlling the motors. When the body frame makes the mop cloth move forward for a predetermined distance, the control device can control and make one of the motors reversely rotate and meanwhile make the other keep normal rotation to further enable the body frame to make the mop cloth turn for a predetermined angle and then keep moving forward.

Abstract: A floor wiping mechanism for mounting in the body of a self-propelled floor cleaner is disclosed to include a frame defining an opening, two rotating shafts suspending in the opening of the frame at two opposite lateral sides in a parallel manner with respective opposite ends thereof positioned in the frame, a wiping cloth made in the form of an endless belt and mounted around the two rotating shafts. When the self-propelled floor cleaner is steering, the floor wiping mechanism is moved with the self-propelled floor cleaner, causing the wiping cloth to wipe the floor.

Abstract: An electronic fence generator includes a cylindrical body, a ground stake downwardly extended from the bottom of the cylindrical body, and an ultrasonic transmitter, an infrared transmitter and an infrared receiver mounted in the cylindrical body. The ultrasonic transmitter is adapted for transmitting an ultrasonic signal to create a collision avoidance range around the cylindrical body. The infrared transmitter is adapted for transmitting an infrared signal in a signal transmitting direction. The infrared receiver is adapted for receiving an infrared signal from another electronic fence generator in a signal receiving direction different from the signal transmitting direction. Thus, the electronic fence generator can be used for creating a virtual electronic fence for restricting an automatic lawn mower to the range defined by the electronic fence.
