[0027] like Figure 1 and Figure 2 As shown, the upper end of the gas generating pipe 8 extends beyond the upper surface of the sealing rubber stopper 3. The upper end of the gas generating pipe 8 is connected to one end of the rubber hose 10. The other end of the rubber hose 10 is connected to the manual double ball joint 11. The lower end of the gas generating pipe 8 extends beyond the lower surface of the sealing rubber stopper 3. The lower end of the gas generating pipe 8 is located inside the glass washing bottle 2.

[0028] like Figure 1 and Figure 2 As shown, the upper end of the infusion tube 9 extends beyond the upper surface of the sealing rubber stopper 3. The upper end of the infusion tube 9 is connected to one end of the plastic hose 15. The other end of the plastic hose 15 is connected to the bottom end of the glass water nozzle 12. The top end of the glass water nozzle 12 is used for spraying liquid. The lower end of the infusion tube 9 extends beyond the lower surface of the sealing rubber stopper 3. The lower end of the infusion tube 9 is located inside the glass washing bottle 2. The lower end of the infusion tube 9 is connected to one end of the water delivery rubber tube 13.

[0031] Specifically, the sealing rubber stopper 3 is used to maintain the airtightness of the laboratory glass washing device.

[0032] Specifically, the bottle holder 1 prevents the glass washing bottle 2 from tipping over.

[0033] Preferably, the exhaust pipe 7 is a short curved glass tube; the gas generating pipe 8 is a short curved glass tube; and the infusion pipe 9 is a short curved glass tube.

Then tighten the sealing rubber stopper 3. Hold the neck of the glass washing bottle 2 with one hand. The anti-slip and heat-insulating protective sleeve 14 at the neck can prevent slipping and overheating of the cleaning solution. Manually block the upper end of the vent pipe 7 with your thumb to ensure good airtightness. With the other hand, continuously press the manual double ball joint 11 to inject gas into the glass washing bottle 2 through the rubber hose 10, increasing the pressure inside the bottle. Under the action of gas pressure, the cleaning solution is delivered through the water delivery rubber hose 13 to the delivery tube 9, and then to the plastic hose 15. Finally, it is sprayed out from the upper nozzle of the glass water flow nozzle 12. Move the glass water flow nozzle 12 to thoroughly rinse the object. When you need to stop, stop pressing the manual double ball joint 11 and release the upper end of the vent pipe 7 with your thumb. The gas pressure inside the bottle is released instantly, and the cleaning solution stops immediately. This can effectively solve the technical problem that the liquid output cannot be stopped immediately in the existing technology. When not in use, the glass washing bottle 2 is placed on the dedicated washing bottle holder 1 to prevent the glass washing bottle 2 from tipping over and causing safety hazards.
