[0032] In this embodiment, in order to achieve the effect of quickly opening the top cover 3 to load and unload the filter element 2, the closed connection assembly 5 is designed. An inner seat 5-1 is arranged at the inner bottom of the outer shell 1, a pair of inner ring layers 5-2 are arranged on the inner wall, the filter element 2 is inserted into the inner ring layer 5-2 and is in sealing fit. An air hood 5-3 with a plurality of air holes 5-4 formed on the outer surface is arranged on the bottom surface of the top cover 3. A docking cover 5-5 is arranged at the bottom of the air hood 5-3, and the bottom of the docking cover 5-5 is sleeved on the inner seat 5-1. After the gas passes through the filter element 2, it exhausts upward through the air holes 5-4, and the gas is concentrated at the top. A column 5-6 is further arranged on the inner seat 5-1, a rectangular block 5-7 is arranged at the upper end of the column 5-6, and the rectangular block 5-7 is hermetically sleeved and connected with the top cover 3. Clamping grooves 5-9 are formed on both sides. A pair of fixing sleeves 5-10 are arranged on the surface of the top cover 3, a movable rod 5-11 and a second spring 5-14 are sleeved inside. A clamping block 5-12 is arranged at one end of the movable rod 5-11. Through the elastic force of the second spring 5-14, the clamping block 5-12 is inserted into the clamping groove 5-9, so as to limit and fix the top cover 3. A pull plate 5-13 is arranged at one end of the movable rod 5-11, and the clamping block 5-12 can be pulled out of the clamping groove 5-9 through the pull plate 5-13. A first spring 5-8 is further arranged inside the docking cover 5-5, which can push the top cover 3 upward through the elastic force to facilitate opening.
