4results about How to "Solve the dripping problem" patented technology

This utility model discloses a drip-proof finished oil filling tank, relating to the field of finished oil filling. It includes an oil storage tank with a drain pipe connected to its bottom end. A valve is installed on the drain pipe, and an oil delivery pipe is connected to its end. A sealing element is installed inside the oil delivery pipe. A fixing frame is fixedly connected to the outer side of the oil delivery pipe, and a connecting frame is fixedly connected to the fixing frame. A rotating shaft is rotatably connected to the connecting frame, and a baffle is fixedly connected to the rotating shaft. A sealing gasket for sealing the outlet of the oil delivery pipe is fixedly connected to the baffle. A rotating component that cooperates with the sealing element is installed on the rotating shaft. This utility model, through the sealing element and the rotating component, after the finished oil filling is completed, causes the sealing gasket to rotate to the end of the oil delivery pipe to seal the end of the oil delivery pipe, preventing residual finished oil inside the oil delivery pipe from dripping. Therefore, it solves the problem in the prior art where residual oil in the oil pipe causes dripping during finished oil filling.

The utility model provides a bathroom faucet, and belongs to the technical field of faucets. The faucet comprises a faucet body with a valve element control end and a water outlet, a containing cavity with a rear opening is formed in the rear end of the faucet body, a rear end cover of the faucet body is provided with a back plate for sealing the rear opening, the back plate is provided with a water inlet used for being communicated with a water inlet pipe, a valve element assembly is arranged in the containing cavity, and the containing cavity comprises an upper cavity wall and a lower cavity wall. A supporting stand column is arranged between the upper cavity wall and the lower wall. The faucet has the advantages that the overall structural strength of the faucet is enhanced, and water accumulation is prevented.

The utility model provides a top spray device of closing and stopping immediately relates to bathroom product technical field, including body, water outlet net and floating panel, the body has water inlet channel and with water outlet cavity of water inlet channel intercommunication, the water outlet net is installed in the body, is equipped with a plurality of water outlet holes on it, the floating panel is equipped with a plurality of water outlet nozzles and with each water outlet hole one -to -one corresponding arrangement's sealing portion, each sealing portion is protruding in the floating panel's one side towards water outlet net, wherein, the floating panel is configured as open water and is under the action of water flow pressure and moves downward, to make sealing portion away from water outlet hole, close water and move upward under the action of elastic part, to make sealing portion block water outlet hole, to control the on-off of water outlet nozzle and water outlet hole. To improve the problem that the existing water stop flower shower stops immediately and the effect is poor.
