Detailed Description

As shown in fig. 1, the utility model provides a cleaning-free oxygen collection device, which comprises the following specific implementation steps: two plastic bottles A8 and B13 each having a volume of 1000 ml were drilled at the bottoms thereof, and glass tubes B9 and C12 were fixed in the holes by using a hot melt adhesive, ensuring a seal free from leakage. Two glass guide pipes B9 and C12 are connected through a 40 cm long latex pipe C11 to form a communicated water seal system, and a water stop clamp C10 is arranged on the latex pipe and used for controlling the flow direction of water between two plastic bottles A8 and B13. And a hole is drilled in the center of the bottle cap of the plastic bottle A8, the T-shaped pipe 4 is installed, and the lower end of the T-shaped pipe 4 is tightly connected with the bottle cap through hot melt adhesive, so that a sealing structure is formed. The left end of the T-shaped pipe 4 is connected to a glass conduit A5 of the oxygen generating device through a latex pipe B7, and a water stop clamp B6 is arranged on the latex pipe B7 so as to control the input of oxygen. The upper end of the T-shaped pipe 4 is connected to the sharp-mouth glass guide pipe 1 through a latex pipe A2, and a water stop clamp A3 is arranged on the latex pipe A2 so as to control the output of oxygen. In use, the plastic bottle A8 filled with water is placed on the laboratory bench, and the empty plastic bottle B13 is placed on the tripod 14 open to remain stable. Closing a water stop clamp C10 on a latex tube C11 between two plastic bottles, opening a water stop clamp B6 connected with a glass guide tube A5 of an oxygen generating device and a water stop clamp A3 connected with a sharp-mouth glass guide tube 1 at the upper end of a T-shaped tube 4, and purifying oxygen.
