[0002] As people's quality of life continues to improve, the demand for food preservation is also increasing. Generally, food ingredients can be stored for a relatively long time in a vacuum environment. Based on this, vacuum extraction equipment for bottles and bags has appeared on the market.

[0003] Mason jars are common sealed containers for storing food in daily life. Due to their fresh appearance, rich sizes and strong plasticity, they have also derived many new uses. The bottle and lid of the Mason jar are separate, and the lid is one-piece, two-piece, etc. At present, some Mason jars use threaded lids to tighten and seal. Although they can achieve a sealing effect, they cannot expel the air in the bottle, which is not conducive to the long-term storage of food in the bottle. Or they use a manual pump or a handheld vacuum pump in combination with a sealing lid to evacuate the air, or they do so by disassembling some parts of the product, which is cumbersome to operate. In order to solve the above-mentioned related problems, automatic vacuum products have appeared on the market, but there are still some problems, such as poor drainage performance, which can easily cause damage to internal parts of the equipment, and low versatility, which affects the practicality of the product.
