Abstract: A dust collector includes a filter frame, a cartridge filter, an end cap, and a cover. The filter frame is provided with a center column. The end cap is provided with a bottom plate, a plurality of sliding slots, a plurality of first side walls, a plurality of baffles extending from the first side walls, and a plurality of clamping members. The cover is provided with a plurality of protruding members and a plurality of extending members. The filter frame includes an accommodating space. The bottom plate is provided with a plurality of through openings that run through the bottom plate. The through openings are disposed opposite to the baffles and are configured to communicate between the sliding slots and the accommodating space. The extending members extend into the through openings. The first side walls are connected between the bottom plate and the baffles.

Abstract: Disclosed is a dust collector that includes a filter frame, a cartridge filter, and an end cap and a cover that are connected to the cartridge filter. The filter frame is provided with a center column. The cover is operative to rotate around the center column along and against a rotating direction. The cover is limited to rotate between a first angular position and a second angular position relative to the end cap. The end cap is provided with a plurality of clamping members. When the cover is located at the first angular position, the plurality of clamping members clamp the center column; when the cover is located at the second angular position, the plurality of clamping members do not clamp the center column. Rotating from the second to the first angular position, the cover pushes the plurality of clamping members towards the center column to clamp the center column.

The cover is provided with a plurality of protruding members and a plurality of extending members. The protruding members are operative to rotate along with the cover along the sliding slots. The filter frame includes an accommodating space configured for accommodating the filter frame. The bottom plate is provided with a plurality of through openings that run through the bottom plate. The through openings are disposed opposite to the baffles and are configured to communicate between the sliding slots and the accommodating space. The extending members extend into the through openings. The bottom plate and baffles are spaced apart.

Abstract: Disclosed is a filter device, including: a filter cage, a filter cartridge sleeved at outer side of the filter cage and an end cap connected to one end of the filter cartridge; the end cap is provided with a through end hole, and one end of the filter cage corresponding to the end cap is provided with a middle column penetrating through the end hole; and the filter device further includes: a cover body installed at outer side of the end cap; where the end cap is provided with a plurality of clamping elements used for pressing against the middle column, and the cover body pushes the clamping elements to move to the middle column in a process that the cover body rotates around the middle column along a rotation direction, so that the middle column is clamped by the plurality of clamping elements.

Abstract: A method of generating power uses a nanoenergetic material. The nanoenergetic material comprising thermite is obtained and deposited on a substrate. An igniter is placed on the nanoenergetic material. When power is desired, the nanoenergetic material is ignited. A transducer receives thermal, sonic, magnetic, optic and/or mechanical energy from combustion of the nanoenergetic material and converts it into electrical energy. Preferably, the transducer is a thermoelectric, piezoelectric or magneto device. Preferably, multiple transducers are integrated in one power generators to maximize the power from nanoenergetic thermites.
