Abstract

A small automatic polishing liquid cleaning device for rigid gas permeable contact lens includes a container; a containing chamber is provided inside the container; an exhaust pipe, and a liquid suction pipe, which communicates with the containing chamber disposed on the container; an outlet end of the exhaust pipe communicates with a vacuum orifice of a vacuum generator via a connector, a gas inlet of the vacuum generator communicates with a pipeline for a compressed gas, and a liquid inlet of the liquid suction pipe is disposed at the bottom of a waste liquid trough.

First claim

What is claimed is:

1. An automatic waste-liquid container system for use with a polishing device for rigid gas permeable contact lenses, comprising:
a container defining an internal containing chamber;
an exhaust pipe communicating with the containing chamber, the exhaust pipe including an inlet end and an outlet end, the inlet end connected to the container; and
a liquid suction pipe communicating with the containing chamber and connected to the container, the liquid suction pipe configured to transport liquid received from a waste liquid trough to the containing chamber of the container;
a compressed gas flow-control assembly configured to receive a compressed gas and to control a flow of the compressed gas;
a vacuum generator having an inlet end and a suction orifice, the inlet end of the vacuum generator connected to the compressed gas flow-control assembly, the suction orifice in communication with the outlet end of the exhaust pipe; and
wherein the vacuum generator is configured to receive the compressed gas from the compressed gas flow-control assembly to generate a suction on the exhaust pipe via the suction orifice, thereby generating a suction pressure in the containing chamber and causing the liquid to flow into the containing chamber from the waste liquid trough.

2. The automatic waste-liquid container system of claim 1 , wherein the compressed gas flow-control assembly includes a gas flow control switch.

3. The automatic waste-liquid container system of claim 2 , further comprising a tap connected to the liquid suction pipe, the tap having at least two interfaces for communication with one or more waste liquid troughs.

4. The automatic waste-liquid container system of claim 2 , wherein a bottom part of the container is provided with a base; a lateral part of the base is provided with a bracket; a supporting plate is fixed on the bracket; and a pressure reducing valve is disposed on the bracket via the supporting plate.

5. The automatic waste-liquid container system of claim 2 , wherein the container comprises a container body and a container cover; and the container body is connected with the container cover in a dismountable way.

6. The automatic waste-liquid container system of claim 1 , wherein the compressed gas flow-control assembly includes a pressure reducing valve; and the pressure reducing valve is provided with a pressure gauge and a pressure adjusting knob.

7. The automatic waste-liquid container system of claim 6 , further comprising a tap connected to the liquid suction pipe, the tap having at least two interfaces for communication with one or more waste liquid troughs.

8. The automatic waste-liquid container system of claim 6 ; wherein a bottom part of the container is provided with a base; a lateral part of the base is provided with a bracket; a supporting plate is fixed on the bracket; and the pressure reducing valve is disposed on the bracket via the supporting plate.

9. The automatic waste-liquid container system of claim 6 , wherein the container comprises a container body and a container cover; and the container body is connected with the container cover in a dismountable way.

10. The automatic waste-liquid container system of claim 1 , further comprising a tap connected to the liquid suction pipe, the tap having at least two interfaces for communication with one or more waste liquid troughs.

11. The automatic waste-liquid container system of claim 10 , wherein a bottom part of the container is provided with a base; a lateral part of the base is provided with a bracket; a supporting plate is fixed on the bracket; and the pressure reducing valve is disposed on the bracket via the supporting plate.

12. The automatic waste-liquid container system of claim 10 , wherein the container comprises a container body and a container cover; and the container body is connected with the container cover in a dismountable way.

13. The automatic waste-liquid container system of claim 1 , wherein a bottom part of the container is provided with a base; a lateral part of the base is provided with a bracket; a supporting plate is fixed on the bracket; and a pressure reducing valve is disposed on the bracket via the supporting plate.

14. The automatic waste-liquid container system of claim 1 , wherein the container comprises a container body and a container cover; and the container body is connected with the container cover in a dismountable way.

15. The automatic waste-liquid container system of claim 14 , wherein an upper surface of the container cover is provided with a non-slip film.

16. The automatic waste-liquid container system of claim 1 , wherein the compressed gas flow-control assembly includes at least one of a gas flow control switch and a pressure-reducing valve.

17. The automatic waste-liquid container system of claim 1 , wherein the inlet end of the exhaust pipe is connected to the container adjacent a top portion of a container body of the container.

18. The automatic waste-liquid container system of claim 17 , further comprising a container cover removably connected to the top portion of the container body.
