Description

Technical Field

[0001] The utility model relates to a quick-connect device, in particular to a magnetic quick-connect device. Background Art

[0002] Currently in the field of cell culture, quick-connect connectors are commonly used to connect the gas supply system between the cell culture device and the honeycomb system. The quick-connect connector is generally composed of a plug and a socket and is used for gas transportation. Its main working principle is: when the plug and the socket in the quick-connect device are combined, the device pipeline is connected to realize gas transportation; when the plug and the socket are separated, the device pipeline is disconnected and gas transportation stops.

[0003] The existing quick connection device has the following problems

[0004] 1. Existing quick-connect devices have extremely high assembly requirements during the manufacturing process, requiring extremely strict guarantees on the verticality and coaxiality of the plug and socket. Furthermore, during use, due to component wear and loosening of the mounting fixtures, the connection is prone to eccentricity, resulting in poor connectivity of the entire pipeline and causing the entire device to malfunction.

[0005] 2. The exposed surface at the end of the plug component of the existing quick-connect device is large, which is easily contaminated by dust particles and other impurities. On the one hand, it will pollute the pipeline gas and have a significant impact on the use of the cell culture device. On the other hand, it will also cause the contact surface between the plug and the socket to be loosely sealed, resulting in gas leakage. Utility Model Content
