Technical Field

[0001] The utility model relates to the field of freezer ventilation, in particular to a ventilation component for a freezer. Background Art

[0002] Freezers, also known as freezers, are mainly used to preserve food and other items at low temperatures. Long-term use of freezers will lead to excessive internal air pressure, which will cause damage. Therefore, a ventilation component is needed to ventilate them. Among them, the "ventilation component for freezers" disclosed in application number "CN202222658927.7" is also an increasingly mature technology. Its "When in use, the utility model is composed of a ventilation component by arranging a valve pipe, a bent pipe, an end cover, and an end box. The valve pipe of the ventilation component is arranged in the exhaust hole of the freezer, and a drying bag is arranged inside the end box. Therefore, when the air pressure in the freezer is lower than the external air pressure, the air will push up the blocking ball in the valve pipe, so that the air pressure inside and outside the freezer is balanced. The arranged end box and drying bag can absorb water vapor in the external air, prevent water vapor from condensing in the valve pipe, avoid the blocking ball from being frozen, and ensure that the ventilation component can always effectively achieve ventilation."
