[0023] In order to prevent the top of the evaporator tank from falling off due to disconnection, a plurality of fixing frames can be installed between the top and the bottom of the evaporator tank to ensure the integrity of the evaporator tank as a whole.

[0024] In this embodiment, an internal thread is provided on the inner ring surface of the fixing sleeve 2, and an external thread is provided on the outer ring surface of the sealing sleeve 3. The sealing sleeve 3 is meshed and connected with the internal thread on the fixing sleeve 2 through the external thread. A retreat space for the sealing sleeve 3 to enter is formed between the fixing sleeve 2 and the evaporator tank body 1. The sealing sleeve can be quickly moved by means of a threaded connection to facilitate cleaning of the filter tube.

[0025] In this embodiment, a plurality of gripping rods 4 are installed on the outer ring surface of the sealing sleeve 3 , and the plurality of gripping rods 4 are arranged away from the fixing sleeve 2 .
