Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of refrigerant recovery and refueling, specifically to a portable refrigerant recovery and refueling device. Background Technology
[0002] The refrigerant recovery and charging machine is a multi-functional machine that integrates recycling, regeneration, vacuuming, charging, and leak detection.
[0003] When refrigerant needs to be added to a car, the refrigerant refill machine needs to be pushed close to the car and then connected to the car for refrigerant filling. However, existing refrigerant refill machines usually place the refrigerant tank directly inside the machine. When pushing the refrigerant refill machine or when human error causes an impact to the refrigerant refill machine, the refrigerant tank may shake or even tip over, affecting the stability of the refrigerant inside the tank and increasing safety risks. To address the aforementioned issues, publication number CN202121406557.7 discloses a cooling medium recirculation filling machine, comprising a machine body, a base plate disposed at the bottom of the machine body, a cooling medium tank movably disposed on the chassis, a first fixing member disposed on one side of the machine body for fixing the cooling medium tank, and a second fixing member disposed on the other side of the machine body, the first fixing member and the second fixing member being detachably connected together; this utility model has a detachably connected first fixing member and second fixing member, which realizes the fixation of the cooling medium tank to the machine body, ensuring that the refrigerant tank will not shake or even fall off when the cooling medium recirculation filling machine is moved or impacted, thereby reducing safety risks. When the refrigerant tank needs to be moved, the connection between the first fixing member and the second fixing member can be directly cut off, facilitating the movement of the refrigerant tank.
[0004] However, the coolant recirculation filling machine still has the following problems: 1. The refrigerant tanks of existing coolant recirculation filling machines are mostly located inside the machine. When replacement is needed, the operation must be carried out inside the machine, which affects the efficiency of refrigerant recovery and filling. Moreover, the location inside the machine makes the overall size of the equipment larger, less portable, and inconvenient to move. 2. Existing coolant recirculation filling machines all use internal pressure detection to detect the refrigerant tank, without weighing detection. It is impossible to quickly detect the weight of the recovered or filled tank, which affects the accuracy of recovery or filling. Utility Model Content
