According to the four-channel oil supply lubricating oil pump, through the combination mode of the electromagnetic relay and the plunger pump, the pump structure can be compact, pulse signals can serve as a pump power source through coil pressurization, the structure is simple, the reliability is high, multi-channel oil supply can be achieved, driving of multiple oil pumps is not needed, and then the low-temperature work requirement is met.

The utility model provides a Chinese style range hood and relates to the technical field of range hoods. The Chinese style range hood comprises a range hood body, a first flow guide mechanism and a second flow guide mechanism which are used for limiting smoke diffusion are installed on the range hood body, the first flow guide mechanism comprises an air curtain machine fixed to the front end of the range hood body, and the second flow guide mechanism comprises two side baffles and a rear baffle. And the rear baffle plate is fixedly connected between the two side baffle plates. According to the device, the air curtain machine is started to vertically blow air downwards to form an air curtain, and under the matching action of the air curtain machine, the side baffles and the rear baffle, oil smoke generated during cooking is prevented from diffusing outwards, so that the smoke is gathered at the bottom of the range hood body, the suction force to the smoke below the range hood body is increased, and the oil suction efficiency and effect of the device are improved; and one end of the movable insertion plate is controlled to be pulled out from the interior of the rectangular frame, so that the whole second flow guide mechanism can be conveniently taken down from the range hood body to be cleaned and maintained.

The utility model discloses a kind of buried town domestic sewage treatment equipment, including processing box, the inside of processing box is separated out collection chamber I and collection chamber II by baffle I and baffle II, filter screen is movably installed between baffle I and processing box side wall, filter screen small mouth end is communicated with inlet pipe by swivel joint, other end is communicated with collection chamber I, filter screen outside is engaged connection by synchronous belt and the synchronous pulley meshing of motor I output end is equipped, lifting frame is equipped in processing box, and electric telescopic link I one end is fixedly connected in the periphery of lifting frame.
