The utility model discloses an oxygen-enriched air supply device in an automobile, which comprises an oxygen-enriched membrane component, the air outlet end of the oxygen-enriched membrane component is connected with a negative pressure pump, the air outlet end of the negative pressure pump is connected with an exhaust mechanism, one side of the oxygen-enriched membrane component is provided with a monitoring control mechanism, and the oxygen-enriched membrane component comprises an air outlet seat. A fan is connected to the end of the air outlet seat, an air outlet is formed in the other end of the air outlet seat, a plurality of vertical adjusting air plates are rotatably connected to the interior of the air outlet seat, and first rotating shafts are fixedly connected to one ends of the vertical adjusting air plates. According to the oxygen-enriched air supply device in the automobile, oxygen-enriched air is generated through the oxygen-enriched membrane assembly, the first motor drives the vertical adjusting air plate to rotate for vertical adjustment, the second motor drives the transverse adjusting air plate to rotate for transverse adjustment, the oxygen-enriched air is blown to a driver, the oxygen concentration in the automobile is effectively improved, and driving fatigue is relieved.

This application belongs to the technical field of medical devices and discloses an airflow switching rotary valve and an oxygen generator. The airflow switching rotary valve includes a mounting base and a moving valve core. The mounting base has a distribution chamber and an air inlet communicating with the distribution chamber. The moving valve core is located inside the distribution chamber and has a moving plate sealing surface. The moving plate sealing surface is provided with an exhaust chamber. The moving valve core is provided with an air inlet channel located on the side of the exhaust chamber. The outer peripheral surface of the moving valve core is provided with multiple contact positions. The contact positions contact the cavity wall of the distribution chamber to restrict the relative movement of the moving valve core with the mounting base in its own radial direction and to restrict the deflection of the moving valve core in its own axial direction. This ensures the sealing performance between the moving valve core and the stationary valve core and reduces the manufacturing cost of the airflow switching rotary valve.

The utility model discloses a catalytic burner for organic matters in a solar photovoltaic panel, which comprises a bottom plate, and the top of the bottom plate is fixedly connected with a pyrolyzing furnace body; the oxygen limiting mechanism comprises a nitrogen cylinder, a barometer, an air supply pipe, an air inlet assembly and an air outlet assembly; the nitrogen cylinder is fixed to the bottom plate, the barometer is fixed to a gas outlet of the nitrogen cylinder, one end of the gas supply pipe is fixedly connected with the end of the nitrogen cylinder, the other end of the gas supply pipe penetrates through the side wall of the pyrolyzing furnace body and is fixedly connected with the pyrolyzing furnace body, and the gas inlet assembly is fixed to one side of the lower end of the side wall of the pyrolyzing furnace body. And the gas outlet assembly is fixed on the other side of the lower end of the side wall of the pyrolyzing furnace body. The oxygen concentration in the pyrolyzing furnace body is kept in an anoxic state all the time, organic matter is decomposed and combusted to generate carbon black, combustible gas can be collected, and meanwhile poisonous gas is prevented from leaking into air.
