The invention discloses a mobile robot man-machine control system based on the face location and flexibility parameters. The system comprises a robot vehicle-mounted control center. The robot vehicle-mounted control center comprises a body motion sensor and an instruction processing center, wherein the body motion sensor is used for collecting image information data so as to obtain data of people within the view in front of a mobile robot and sending the data to the instruction processing center; the instruction processing center is used for extracting the head and / or eye data from the data of people as the judgment basis for gaining of the instruction control right, so that a person who meets the condition of authority becomes a certigier to gain the control right of the mobile robot; and the instruction processing center is also used for extracting the head and / or face data from the data of the certigier as the flexibility parameters so that the head rotating motion of the certigier can be recognized, or as corresponding instruction content so as to control the stop and waiting, the walking direction and the corresponding receding direction of the mobile robot. The mobile robot man-machine control system is high in instruction anti-jamming capability, widely applicable to indoor spaces, high in interaction control accuracy, natural, flexible and high in comfort of user experience.

The invention provides an intelligent accompanying pet feeding equipment that prevents pets from being randomly operated. It includes a main body of the accompanying pet equipment. The upper and lower ends of the inside of the box are movable with a circular plate, the bottom of the pressing plate is fixedly connected with a push plate outside the gear, the inside of the control seat is slidingly inserted with a slide plate, and the left side of the trigger plate is fixedly connected with a push plate corresponding to the push plate. the bezel. When the pet comes to eat, press the pressing plate to move down, the push plate pushes the baffle to the right through the slope, the trigger plate touches the feeding switch, and the pet food will come out, and the push plate drives the gear and the turntable to rotate through the tooth segment , so that the leaky box rotates, and the device returns to the initial state. By setting the leaky box, the shortest feeding interval for the pet is ensured. By setting the push plate and the baffle, it is effective to avoid the random operation of the pet, resulting in the problem of overeating.

The invention relates to the technical field of water dispensers, and provides a water outlet adjustment assembly, a water dispenser and refrigeration equipment. Wherein, the water outlet adjustment assembly includes: a water outlet valve, a control member, a support member and a lock member, the control member is used to drive the water outlet valve to open or close; the support member is connected to the valve housing of the water outlet valve; the lock member can optionally Switch between a locked position and an unlocked position; the lock is located at the locked position, the operating member is limited to the lock, and the lock is limited to the support to prevent the operating member from opening the The water outlet valve moves in the direction; the lock is located at the unlocking position, and the limit of the lock to the control member is released. The water dispenser includes the water outlet adjustment assembly, and the support member is configured as a housing of the water dispenser. The refrigeration equipment includes the water dispenser. The water outlet regulating assembly, the water dispenser and the refrigeration equipment provided by the invention have the function of a child lock, have fewer components, simplify the structure, and help reduce product costs.

The invention discloses a screen locking key system for a numerical-control machine tool. The screen locking key system comprises a screen display module, a screen signal acquisition module, a locking module, a password authentication module and an unlocking module. The screen display module is used for displaying state information of the locking key system on a screen, the screen signal acquisition module is used for acquiring a trigger signal of the screen operated by a user, judging content of the signal and responds corresponding to the content of the signal, the locking module receives a locking request of the screen signal acquisition module and enables the screen to enter a locked state, the password authentication module receives an unlocking request of the screen signal acquisition module and enters a password authentication state, and the unlocking module receives an unlocking request of the password authentication module and releases the screen from the locked state. The screen locking key system is applied to the numerical-control machine tool, misoperation to the touch screen of the machine tool can be prevented, and production safety is improved.
