[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 An experimental anti-backflow glass bottle includes a glass bottle 1 with two glass tubes 2, wherein the longer glass tube 2 is the liquid inlet (located in...). Figures 1 to 3 (Right side), the bottom of the glass tube 2 is directly inserted inside. The short glass tube 2 is the liquid outlet. Each glass tube 2 is equipped with a valve 3. Instruments manufactured by Xinweier Company are selected. The port of the imported glass tube 2 is connected to a Tesla valve 5 through a silicone hose connector 4. The silicone hose connector 4 is selected according to the diameter of the Tesla valve 5 and the port of the glass tube 2. For example, in this application, a straight silicone hose connector 4 with the same diameter is selected. The other end of the Tesla valve 5 can also be equipped with a silicone hose connector 4, or it can be directly connected through a laboratory silicone tube. A telescopic rod is rotatably connected to one side of the Tesla valve 5. The end of the telescopic rod away from the Tesla valve 5 is equipped with a suction cup 13 that can be raised and lowered for adsorbing onto the upper end of the glass bottle 1.

[0021] Specifically, the telescopic rod includes a sleeve 7 and a support rod 6 slidably connected to one end of the sleeve 7. The end of the support rod 6 away from the sleeve 7 is rotatably connected to the side wall of the Tesla valve 5. The sleeve 7 and the support rod 6 are temporarily fixed by a tightening bolt 10 threadedly connected to the end of the sleeve 7.

[0022] Specifically, in combination Figure 2 As shown, in order to prevent the support rod 6 from sliding out of the sleeve 7, a groove 8 is provided at the lower end of the sleeve 7, and a slider 9 is slidably connected in the groove 8. The slider 9 is fixedly connected to the lower end of the support rod 6 located in the sleeve 7, so as to ensure that the support rod 6 and the sleeve 7 will not separate.

The suction cup 13 is fixedly connected to the lower end of the cylinder 12 to realize the adjustment of the vertical position of the suction cup 13. There are many types of suction cups 13, and users can choose according to cost. They will not be described in detail here.

[0024] Installation method: First, insert the silicone hose connector 4 into the glass tube 2, then insert the Tesla valve 5 into the upper end of the silicone hose connector 4. After insertion, tighten the top bolt 10, then rotate the threaded rod 11 to adjust the position of the suction cup 13 so that the suction cup 13 is attached to the upper end of the glass bottle 1. Use the suction force of the suction cup 13 to install the Tesla valve 5 and ensure the stability of the Tesla valve 5 installation.
