4results about How to "Will not be polluted" patented technology

This application relates to the field of quick-freezing technology, and more particularly to a quick-freezing device for quickly freezing items. The quick-freezing device includes a base, an evaporation assembly fitted onto the base, an air duct assembly connected to the evaporation assembly, a detachable storage assembly, and an outer cover surrounding the base and the air duct assembly. In use, the user can place the food items to be quick-frozen into the detachable storage assembly (which is in a disassembled state), then install the detachable storage assembly into the quick-freezing device and perform the quick-freezing operation on the items placed inside. This detachable design makes the quick-freezing process safer.

The utility model discloses a split type water storage and purification all-in-one machine which comprises a vertical mounting plate, the front surface of the vertical mounting plate is fixedly connected with a horizontal placing plate, the upper surface of the horizontal placing plate is fixedly connected with horizontal guide rails, and the horizontal guide rails are symmetrically distributed at the left end and the right end of the horizontal placing plate; the rear end of the horizontal guide rail is fixedly connected with a first bidirectional motor, and the output end of the first bidirectional motor is in threaded connection with a horizontal sliding block through a horizontal lead screw. A horizontal guide rail, a bidirectional motor, a horizontal lead screw, a horizontal sliding block, a case, a vertical mounting groove, a lifting guide rail, a vertical lead screw, a lifting sliding block and a water purifier form a horizontal and lifting combined adjusting mechanism, the water purifier can be moved out of the case, maintenance is facilitated, complex disassembly and assembly operation is avoided, and convenience is provided for daily maintenance; the closed structure is adopted, the water storage tank is installed in the machine box, water can be conveyed to the water storage tank to be stored after being purified, the water cannot be polluted by the outside, and the quality of the water is guaranteed.

The utility model discloses a water body sample uniform liquid distribution device which comprises a sample barrel, the top of the sample barrel is fixedly connected with a water pump through a bolt, the output end of the water pump is provided with an electric metering valve, the other end of the electric metering valve is communicated with a conveying pipe, and the outer wall of the sample barrel is rotationally connected with a movable disc through a sealing bearing. A sealing device is arranged above the movable disc, and the sealing device comprises a plurality of mounting pieces which are annularly and fixedly connected to the top of the movable disc at equal intervals. The utility model relates to the technical field of uniform liquid separation of a water body sample, through the cooperation among a liquid separation barrel, a rubber pad and a connecting pipe, when the water body sample collected in a sample barrel is subjected to uniform liquid separation through an electric metering valve, the water body sample can generate pressure on the rubber pad when flowing into the connecting pipe; when the water in one liquid separation barrel reaches a certain amount of water, the water can flow into the liquid separation barrel, and then the water can flow into the liquid separation barrel through the gaps formed in the sides, attached to each other, of the rubber pads.

The invention discloses an anesthesia reuse instrument postoperative moisturizing and anti-drying pretreatment system which comprises a treatment cabin and an atomization assembly, one side of the treatment cabin is connected with the atomization assembly through a first pipeline, the other side of the treatment cabin is connected with a vacuum pump through a second pipeline, a three-way pipe is arranged in the first pipeline, and a three-way pipe is arranged in the second pipeline. A check valve is arranged at a first port, connected with the treatment cabin, in the three-way pipe, a second port of the three-way pipe is connected with the vacuum pump through a third pipeline, and a gas-liquid separator is arranged in the third pipeline. Used anesthesia instruments are placed on the mesh tray of the treatment cabin, the cabin body is in a negative pressure state through vacuum pumping of the vacuum pump, liquid in the liquid storage tank can be atomized through the ultrasonic atomization piece, accordingly, the atomized liquid is adsorbed into the treatment cabin by negative pressure to clean the anesthesia instruments, manual cleaning is not needed, and the treatment cabin is simple in structure and convenient to use. Meanwhile, the check valve can prevent atomized liquid from flowing backwards, and it is guaranteed that the liquid storage tank is not polluted.
