A lid-opening apparatus for a dust collector includes a base installed on a lid, a controller connected on the base, a cord defining a first end associated with a conduit and a second end associated with the frame, and a limiting member associated with the cord and between the first end and the second end of the cord. The controller can be rotated to a first position and a second position. While the controller is in the first position, the cord is in a loose condition, a flexible portion of the conduit is stretched, and the lid seals the container. While the controller is in the second position, the cord is in a tight condition, the flexible portion of the conduit shortens, and the lid leaves the container.

1. A lid-opening apparatus for a dust collector including a container, a lid sealable with the container, and a conduit in fluid communication with the container through the lid, the lid-opening apparatus comprising: a base adapted to be installed on the lid;a controller installed on the base;at least one cord including a first end adapted to be connected with the conduit and a second end connected with the controller; anda limiting member adapted to be installed on the lid, wherein the limiting member abuts with and is located between the first end and the second end of the at least one cord;wherein the controller is rotatable between a first position and a second position, wherein the at least one cord is in a loose condition with a flexible portion of the conduit being stretched and the lid sealing the container when the controller is in the first position, and wherein the at least one cord is in a tight condition with the flexible portion of the conduit shortened and the lid leaving the container when the controller is in the second position. 2. The lid-opening apparatus for the dust collector as claimed in claim 1, wherein the at least one cord comprises two cords with the first ends of the two cords respectively associated with two sides of the conduit and the second ends of the two cords respectively associated with two sides of the controller. 3. The lid-opening apparatus for the dust collector as claimed in claim 2, wherein the base includes a first portion adapted to be installed on the lid and a second portion for extending away from the lid, wherein the controller includes a frame and a handle, with the frame defining a proximal end connected to the second portion of the base and the handle and a distal end, wherein the handle crosses over the distal end of the frame. 4. The lid-opening apparatus for the dust collector as claimed in claim 3, wherein the frame is substantially T shaped. 5. The lid-opening apparatus for the dust collector as claimed in claim 3, wherein the first portion forms a grip for a user to take the lid up by grabbing the grip. 6. The lid-opening apparatus for the dust collector as claimed in claim 3, wherein the second portion is perpendicular with respect to the first portion. 7. The lid-opening apparatus for the dust collector as claimed in claim 3 further including two receiving portions respectively formed on two sides of the distal end of the frame, with the second ends of the two cords being respectively wound on the two receiving portions. 8. The lid-opening apparatus for the dust collector as claimed in claim 7 further including a bolt inserted through the distal end of the frame, and a nut screwed on the bolt, wherein one of the two receiving portions is formed between the frame and a head of the bolt, and wherein another of the two receiving portions is formed between the frame and the nut. 9. The lid-opening apparatus for the dust collector as claimed in claim 2 wherein the base includes a first portion adapted to be installed on the lid and a second portion extending away from the lid, wherein the controller includes a frame and a handle, wherein the frame has a fastener connected thereon, with the frame being pivotally assembled on the second portion of the base by the fastener, wherein the handle is associated with an edge of the fastener, wherein the second ends of the two cords are respectively associated with two sides of the fastener of the frame, and wherein the handle is rotated and the fastener is rotated to enable the two cords to be wound.
