Provided is an environment-friendly mobile collecting box for decoration cutting dust. The mobile collecting box comprises a box body, wherein a water tank is fixedly mounted on one side of the bottomsurface of the inner wall of the box body, the bottom surface and the outer side of the water tank are fixedly connected to the inner wall of the box body separately, the inner side of the water tankis fixedly connected to one side of the box body, and openings are formed in the top surface and the other side of the box body; a first through hole is formed in the bottom of the inner side of theinner wall of the water tank, a switching valve is disposed in the first through hole, and a second through hole is formed in one side of the box body; the interior of the first through hole communicates with the interior of the second through hole, and the second through hole communicates with the interior of the box body; the top surface of the water tank is fixedly connected to one end of a hose, and the other end of the hose is arranged in the box body, and a floating plate is fixedly mounted on the periphery of the other end of the hose. Sediment in the box body can be pushed directly into the garbage bag through cooperative use of a mud box and a garbage bag, and the mud box can be taken and placed freely; after the mud box is taken out, a sealing cap of the garbage bag containing the sediment is removed, and after the garbage bag is replaced by a new garbage bag, the mud box is put back, and the sediment is not in contact with the mud box, and cleaning of the mud box by a user is not needed, so that time and labor are saved.

The invention discloses a molecular film type automotive nitrogen and oxygen separation device which comprises a turbocharger, a nitrogen and oxygen separator, a gas inlet valve, a gas outlet valve, a negative pressure pump and an electric control throttling valve. The turbocharger is driven by a turbine in an automobile turbocharger, so that the air is compressed to be conveyed to two paths of the nitrogen and oxygen separation device, the nitrogen and oxygen separation device can separate oxygen from the air, the air with high oxygen content is output, and the air is supplied to an engine for use through the gas outlet valve. The two paths of the nitrogen and oxygen separation device work alternately, when the temperature of the two paths of the nitrogen and oxygen separation device is too high to influence oxygen production efficiency, a main air inlet pipeline is opened to provide air normally by controlling the opening degree of the electric control throttling valve, and thus the phenomena of gas circuit plugging and engine stalling are avoided. According to the automotive nitrogen and oxygen separation device, the two branch paths work alternately, high concentration oxygen can be supplied to the engine continuously so that fuel can burn and act, and the burning utilization rate of the fuel is improved.
