The present invention also relates to an operating method of a household device for replacing contact lens liquid, the present invention can realize automatic storage, automatic liquid adding, automatic liquid discharge, and automatic cleaning of contact lenses, and belongs to the technical field of contact lens cleaning.

The utility model relates to the field of milk purification, in particular to a milk purification device for milk powder production, which aims at solving the technical problems that most of the existing vertical centrifugal milk purification equipment carries out milk injection, centrifugation, liquid discharge and impurity discharge according to working procedures and cannot realize continuous production, and comprises a shell, a cleaning shaft is rotatably arranged at the axis of the top wall of the shell, and a liquid injection channel is formed in the upper surface of the cleaning shaft; the top wall of the shell is rotationally connected with a filter screen support, a gap is reserved between a filter screen body and the inner wall of the shell, the distance between the outer end of the liquid drainage channel and the axis is not smaller than two thirds of the radius of the filter screen, and a spiral scraper blade is arranged between the outer end of the liquid drainage channel and the filter screen. Emulsion is guided to be discharged to the filter screen through the liquid discharging channel and then is centrifugally discharged by the filter screen rotating at a high speed, the emulsion cannot flow into the filter screen through the bottom, impurities on the inner wall of the filter screen are brushed down by the spiral scraper and the spiral blade and are played out through the impurity outlet hopper, and continuous purification is completed.

The utility model relates to the technical field of control valves, in particular to a spaceflight manual stop valve which comprises a valve body, the bottom end of the valve body is connected with a first connecting port in a penetrating mode, the outer wall of the valve body is connected with a second connecting port in a penetrating mode, a blocking groove is formed in the valve body, and an unloading groove is formed in the top end of the blocking groove. And the inner wall of the unloading groove is slidably connected with a sealing part, a first ball valve is arranged in the inner wall of the second connecting port, and a second ball valve is arranged in the inner wall of the first connecting port. According to the utility model, through the mutual combination of the first rotating handle, the second rotating handle, the first ball valve and the second ball valve, no matter which connecting port is used, the other connecting port can be closed, so that the stop valve forms a relatively closed space, and therefore, high-pressure gas cannot be wasted due to reverse flow, and the service life of the high-pressure gas is prolonged. The high-pressure bearing effect of the stop valve is greatly improved.

The utility model relates to the technical field of liquefied gas recovery equipment, in particular to a device for recovering residual gas in a liquefied gas pipe, which comprises a connecting hose and a hanging plate, the rear end of the connecting hose is fixedly connected with a first connector, the front end of the connecting hose is fixedly connected with a second connector, and the lower part of the right end of the hanging plate is fixedly connected with a placing box. A recycling mechanism is movably connected to the inner surface of the placing box; the recycling mechanism comprises a recycling tank, and the middle of the upper end of the recycling tank is fixedly connected with a fixing pipe. According to the device for recovering the residual gas in the liquefied gas pipe, the recovery mechanism is fixedly connected to the rear part of the outer surface of the connecting hose, and the connecting hose is connected between a liquefied gas storage tank and a gas stove for use; a micro pump can be controlled by a control switch in the recycling mechanism to recycle the residual liquefied gas in the connecting hose into the recycling tank, waste is avoided, and the recycled liquefied gas cannot be discharged automatically due to the arrangement of a one-way valve in the recycling mechanism.

This application relates to a shift register, a gate driving circuit and its driving method, and a display panel. The shift register includes: an input module; a control module including a first switching unit, a second switching unit, and an energy storage unit, wherein the control terminal of the first switching unit receives a first control signal, the second terminal of the first switching unit is electrically connected to the first terminal of the energy storage unit and the second terminal of the second switching unit, the control terminal of the second switching unit receives a second control signal, and the first terminal of the second switching unit receives a second power supply signal; and an output module; in a first sub-stage of the holding phase, the first switching unit is turned off under the control of the first control signal, and the second switching unit is turned on under the control of the second control signal, so that the voltage levels of the first terminal and the third terminal of the energy storage unit remain consistent. Using the above-mentioned shift register, the energy storage unit can be controlled to not charge or discharge in the first sub-stage, thereby reducing power consumption.
