DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) A preferred embodiment of a forcing and fixing structure for the filter cylinders of a filter cylinder type dust collector in the present invention, as shown in FIGS. 3-6, includes a dust collector 300, a plurality of setting racks 60, a plurality of forcing rods 70, a locking member 80 and a plurality of assembling-and-disassembling plates 90 combined together.

(12) The dust collector 300 consists of a housing 10 having its interior formed with an accommodating space and its topside provided with an air outlet 12 communicating with the accommodating space 11. The housing 10 has one side bored with an air intake 13 communicating with the accommodating space 11 and another side provided with a door plank 14 assembled thereon with a container type door handle 15. The accommodating space 11 of the dust collector 300 has an upper side installed with a motor fan 20 and an intermediate section provided with a division plate 30, which is bored with a plurality of through holes spaced apart and in this preferred embodiment, the division plate 30 has its underside provided with a plurality of annular projecting edges 32 respectively positioned at the circumference of the through holes 31. Further, plural filter cylinders 40 respectively corresponding with the through holes 31 are positioned under the division plate 30, and a plurality of dust collecting barrels 50 are provided beneath the filter cylinders 40.

(13) The setting racks 60 are in pair and in parallel provided under the division plate 30, respectively and axially bored with an accommodating groove 61.

(14) The forcing rods 70 corresponding with the setting racks 60 are in pair received in the corresponding accommodating groove 61, and the sections of the forcing rods 70 are unequal diameter and formed with a major diameter section 71 and a minor diameter section 72. Further, the forcing rods 70 respectively have one end vertically connected with a rotary handle 73, and the rotary handles 73 corresponding with the forcing rods 70 are provided in pair and can be firmly locked in place by a locking member 80, which is a screw in this preferred embodiment.

(15) The assembling-and-disassembling plates 90 are respectively fixed on the twinned forcing rods 70 and respectively bored with a plurality of openings 91 corresponding with the through holes 31 for the filter cylinders 40 to be respectively inserted therein.

(16) For further understanding the structural features, the use and method of technology and the expected effect to be achieved of this invention, the way of use of this invention is stated as follows:

(17) Referring to FIGS. 7-9 as well as FIGS. 3-6, to assemble the filter cylinders 40 in the housing 10, firstly, have the filter cylinders 40 respectively fitted in the openings 91 of the assembling-and-disassembling plates 90. In this preferred embodiment, each filter cylinder 40 has its topside provided with a holding member 42 having an upper side fixed with an airtight member 42, which is foam and which is bored with a through hole 421, the bore size of the through hole 421 being smaller than the through hole 31 of the division plate 30. At this time, the holding member 41 of the filter cylinder 40 is positioned on the assembling-and-disassembling plates 90 for engaging and fixing the filter cylinder 40 in the opening 91. Subsequently, turn the container type handle 15 to open the door plank 14 and have the forcing rods 70 respectively received in the accommodating grooves 61 of the setting racks 60 and thus, the assembling-and-disassembling plates 90 assembled with the filter cylinders 40 can be placed in the housing 10. When the rotary handles 73 of the forcing rods 70 are not yet locked in place, referring to FIGS. 7 and 8, the assembling-and-disassembling plates 90 are laid on the twinned forcing rods 70, and a gap is formed between the filter cylinder 40 and the division plate 30. At this time, a user can turn the twinned rotary handles 73 to actuate the forcing rods 70 to rotate and force the assembling-and-disassembling plates 90 to move upward. When the forcing rods 70 are rotated and their major diameter sections are perpendicular to the underside of the assembling-and-disassembling plates 90, the topside of the airtight member 42 of the filter cylinder 40 will be forced to tight fit with the annular projecting edge 32 of the division plate 30 and then, have the twinned rotary handles 73 of the forcing rods 70 firmly locked in place by the locking member 80. Thus, an airtight and seamless state can be maintained between the filter cylinder 40 and the division plate 30 so that when the dust collector 300 is operated, dust and chips sucked in through the air intake 13 will be impossible to pass through the division plate 30 and be exhausted out of the air outlet 12.

(18) To replace or wash clean the filter cylinders 40, only unscrew the locking member 80 and turn the twinned rotary handles 73 to actuate the forcing rods 70 to rotate, letting the assembling-and-disassembling plate 90 move downward. When the minor diameter sections 72 of the forcing rods 70 are perpendicular to the underside of the assembling-and-disassembling plates 90, as shown in FIG. 8, the assembling-and-disassembling plate 90 assembled thereon with the filter cylinders 40 can be removed out of the housing 10.

(19) Thus, when the filter cylinder 40 are to be assembled in or disassembled from the dust collector 300, the twinned rotary handles 73 are turned to actuate the forcing rods 70 to rotate and force the filter cylinders 40 to tight fit with the division plate 30 by the unequal diameter twin forcing rods 70. By so designing, this invention is able to enhance convenience in assembly and disassembly of filter cylinders, attain good airtight effects and further enhance efficacy of air purification and quality of use of the filter cylinder type dust collector.

(20) While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
