The middle filter cartridge is sleeved with a collecting barrel body, the top outer side wall of the collecting barrel body is provided with an extending edge which extends outwards in the radial direction, the extending edge is pressed on the top end face of the middle filter cartridge, the bottom face of the extending edge is provided with a plurality of protruding columns, the protruding columns are inserted in positioning concave holes formed in the top end face of the middle filter cartridge, a plurality of vertical circulation holes which are uniformly distributed by taking the central shaft of the middle filter cartridge as the center are formed in the top end face of the middle filter cartridge, the upper ends of the vertical circulation holes are communicated with the transition cartridge, and the lower ends of the vertical circulation holes are communicated with.
The collecting barrel body is a conical barrel body with a small bottom diameter and a large upper diameter.
The protruding column is adsorbed in the strong magnet block fixed in the positioning concave hole.
The top end outer side wall of the air inlet cylinder is provided with a first radial extending edge, the top of the middle filter cylinder is provided with a second extending edge extending outwards in a radial direction, the bottom end outer side wall of the filter cylinder is provided with a third extending edge extending outwards in a radial direction, and the first radial extending edge, the second extending edge and the third extending edge are mutually pressed and fixedly connected through bolts.
The beneficial effects of the utility model reside in that:
it can install in exhaust and go out tobacco pipe department, directly convulsions through the exhaust fan for the flue gas discharges after filtering, makes impurity such as oil in the cigarette and dust filter, reduces the influence to the surrounding environment, has environmental protection effect.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a partial enlarged view of the present invention.
The specific implementation mode is as follows:
example (b): as shown in fig. 1 to 2, an automatic-ventilation-type environmental-friendly filter cartridge comprises an air inlet cylinder 1, an exhaust fan 2 and a transition cylinder 4, wherein the top end of the air inlet cylinder 1 is connected with a middle filter cartridge 3, the top of the middle filter cartridge 3 is connected with the lower end of the transition cylinder 4, and the upper end of the transition cylinder 4 is connected with the exhaust fan 2;
the middle part inside wall of a transition section of thick bamboo 4 has protruding circle 41, and the top lateral wall of filter sleeve 6 has the filtration extension limit 62 of outside radial extension, filters extension limit 62 and presses on protruding circle 41 and pass through bolt fixed connection on protruding circle 41, and the top end face and the bottom end face of filter sleeve 6 all are fixed with metal filters 63, and two metal filters 63 cover the top and the bottom of filter sleeve 6 respectively, and the middle part packing of filter sleeve 6 has molecular sieve 61, and the centre gripping of molecular sieve 61 is at two metal filters 63.
Furthermore, the middle filter cartridge 3 is sleeved with a collecting barrel body 5, the top outer side wall of the collecting barrel body 5 is provided with an extending edge 51 which extends outwards and radially, the extending edge 51 is pressed against the top end surface of the middle filter cartridge 3, the bottom surface of the extending edge 51 is provided with a plurality of protruding columns 52, the protruding columns 52 are sleeved in the positioning concave holes 31 formed in the top end surface of the middle filter cartridge 3 in an inserting manner, the top end surface of the middle filter cartridge 3 is provided with a plurality of vertical circulation holes 32 which are uniformly distributed by taking the central shaft of the middle filter cartridge 3 as the center, the upper ends of the vertical circulation holes 32 are communicated with the transition cartridge 4, and the lower ends of the vertical circulation holes 32 are communicated with the.
Further, the collection barrel 5 is a tapered barrel with a smaller bottom diameter and a larger upper diameter.
Further, the protruding column 52 is absorbed in the strong magnet block 33 fixed in the positioning concave hole 31.
Further, the top end outer side wall of the air inlet cylinder 1 is provided with a first radial extending edge 11, the top part of the middle filter cylinder 3 is provided with a second extending edge 34 extending radially outwards, the bottom end outer side wall of the transition cylinder 4 is provided with a third extending edge 42 extending radially outwards, and the first radial extending edge 11, the second extending edge 34 and the third extending edge 42 are pressed against each other and fixedly connected through bolts.
The working principle is that the exhaust fan 2 operates to suck smoke, the smoke enters the transition cylinder 4 through the vertical circulation hole 32 after entering the air inlet cylinder 1, then is filtered through the molecular sieve 61 in the filtering sleeve 6 to filter oil smoke and dust, and finally is discharged from the exhaust end of the exhaust fan 2, wherein all parts of the smoke can be detached, so that the molecular sieve 61 can be replaced, and the exhaust fan is very convenient.
