Adapter assembly

An adapter assembly, comprising:

• a main pipeline, configured to circulate gas or liquid, the main pipeline comprising an extended pipeline and a connection pipeline, one end of the connection pipeline being in communication with and integrally formed with one end of the extended pipeline to form a whole pipe, the other end of the extended pipeline forming an outlet;
• and
• an adapter pipeline, wherein the adapter pipeline is provided with a near end and a far end opposite to the near end;
• the far end of the adapter pipeline is configured to be detachably connected to a vacuum cleaner or a water faucet, and the near end of the adapter pipeline is integrally formed with the other end of the connection pipeline through a selected molding process from a group consisting of a secondary injection molding, a hot bonding, and a solvent bonding, with the other end of the connection pipeline having an inlet located in the adapter pipeline, and the inlet configured to be communicated with the vacuum cleaner or the water faucet, such that the adapter pipeline and the main pipeline form a sealing connection to avoid a gas leakage or a liquid leakage at a connection position between the adapter pipeline and the main pipeline,
• wherein both of the extended pipeline and the connection pipeline are made of the same material, a length of the extended pipeline is greater than a length of the connection pipeline, and is greater than a length of the adapter pipeline, the material of the main pipeline is different from the material of the adapter pipeline, both of the material of the main pipeline and the material of the adapter pipeline are flexible material, and a flexibility of the adapter pipeline is greater than a flexibility of the main pipeline.
