This invention discloses a waste filtration and collection device for a swimming pool underwater cleaning robot, comprising: a shell with an inlet channel and an outlet channel; the inlet channel having a confluence channel and two suction channels; the two suction channels are located at the bottom of the shell and converge to the lower end of the confluence channel; the upper end of the confluence channel extends into the inner cavity of the shell and divides the inner cavity into front and rear waste compartments; the outlet channel has a drain channel and two filter channels; the drain channel is located at the top of the shell, with a water pump impeller installed at the drain outlet at the upper end of the drain channel, and its lower end confluences and connects to the upper ends of the two filter channels; the lower ends of the two filter channels are equipped with filter screens, which correspond to the inlets of the front and rear waste compartments respectively; both ends of the confluence channel are gradually expanding openings, with the upper end guiding the flow direction towards the front and rear filter screen areas respectively. This invention can effectively reduce the flow resistance of the entire channel, reduce the power consumption of the swimming pool cleaning robot, and thus extend the effective working time of the robot.

The utility model discloses a single oil duct type open gear automatic oil distribution device, which belongs to the technical field of gear oil distribution, and comprises a base and an oil distribution component, the base is connected with a sliding platform through a sliding component, and the base is provided with a telescopic component; the oil distribution component comprises an oil distribution block, a shaft body and a return spring, the oil distribution block is integrally in a gear tooth shape, a cylindrical through hole is formed in the oil distribution block, an annular oil channel is formed in the cylindrical through hole, a linear oil channel is formed in the oil distribution block, a penetrating channel is formed in the oil distribution block, and a moving block is arranged in the penetrating channel; two oil outlet notches are formed in the side face, facing the cylindrical through hole, of the movable block, lubricating grease is sequentially discharged through the oil injection channel, the annular oil channel and the linear oil channel, the lubricating grease is evenly smeared on the surface of the exposed gear to be subjected to oil supplementation, the shutdown time is omitted in the mode that smearing is conducted along with operation of the exposed gear, the effective working time of equipment is prolonged, and the working efficiency is improved. And the problem that the lubricating grease smearing effect is poor through traditional manual work is solved.
