[0002] A refrigerator is a household appliance that uses electricity to refrigerate and keep food and beverages fresh. It lowers the internal temperature through the circulation of refrigerant, thus achieving preservation and refrigeration. According to the industry standard "Safe Service Life of Household Appliances Part 1: Household Refrigerators" jointly formulated by the China Household Electrical Appliances Association and other organizations, the safe service life of household refrigerators is 10 years. Manufacturers are required to clearly label the service life and safety warnings on the product, detailing the start date of the service life, the risks of exceeding the service life, and the termination conditions. Refrigerators must be replaced after reaching their service life. To reduce environmental pollution and improve resource utilization, it is necessary to recycle used refrigerators. The refrigerant and other harmful substances in used refrigerators pollute the environment; therefore, during the recycling process, it is necessary to collect the Freon inside the refrigerator. Existing Freon collection devices typically use a needle-piercing method, inserting the needle into the refrigerant pipe and extracting the refrigerant through the needle hole. However, the small area of ​​the needle hole results in low Freon collection efficiency, and the needle piercing point is in an external, natural state, posing a risk of leakage.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content
