Description

Technical Field

[0001] The utility model relates to a wine cabinet, in particular to a double glass plate of the wine cabinet. Background Art

[0002] Currently, the existing technology, Chinese Patent No. 201620859826.8, relates to the field of insulating glass. This invention addresses the issues of internal and external pressure balance and internal condensation in existing insulating glass products. The utility model provides an explosion-proof insulating glass, comprising a first glass layer and a second glass layer, separated by a sealing frame. The first and second glass layers, along with the sealing frame, form a gas chamber. The utility model also includes a balancing valve, comprising a valve body having a vent opening that connects the gas chamber to the outside world. A hose is disposed within the vent opening. When the pressure difference between the gas chamber and the outside world is the same, the hose seals the vent opening, preventing airflow from flowing between the gas chamber and the outside world. When the pressure difference between the inside and outside of the gas chamber reaches a first threshold, the hose is pushed open by the airflow, allowing airflow between the gas chamber and the outside world. However, the problem is that the threshold control of the internal and external pressure difference using a hose is highly regional and difficult to universally apply. Utility Model Content
