1. Field of the Invention
The present invention relates to a vacuum collector or dust collector, and more particularly to a vacuum collector or dust collector having a dust collection barrel or dust collecting receptacle detachably secured to the dust collector for allowing the dust collecting receptacle to be easily removed or disengaged or moved away from the dust collector and for allowing the dust received or collected within the dust collecting receptacle to be easily and quickly cleaned or dumped from the dust collecting receptacle.
2. Description of the Prior Art
Typical vacuum or dust collectors comprise an array of drum filters and a frame disposed in a permanent operative position proximate the array, and a number of longitudinal members operatively disposed on the frame for receiving and filtering and collecting the dirt, and suction nozzles extended from tubes for drawing and collecting the dirt.
For example, U.S. Pat. No. 7,201,785 to Lin, the present inventor discloses one of the typical vacuum collectors having a dust collection barrel for collecting the dirt or the dust, and having a vacuum device for drawing the dirt or the dust into the dust collection barrel.
However, after the dirt or dust drawing or collecting operations, or when it is required to clean or dump the dust collection barrel, it will be difficult to remove or disengage or move the dust collection barrel away from the dust collector.
In addition, no pressing or locking or positioning devices have been provided for pressing or locking or anchoring the cover to the dust collection barrel such that the cover may have a good chance to be disengaged from the dust collection barrel while conducting the vacuuming operations.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional vacuum or dust collectors.
The primary objective of the present invention is to provide a vacuum or dust collector including a dust collection barrel or dust collecting receptacle detachably secured to the dust collector for allowing the dust collecting receptacle to be easily removed or disengaged or moved away from the dust collector and for allowing the dust received or collected within the dust collecting receptacle to be easily and quickly cleaned or dumped from the dust collecting receptacle.
The other objective of the present invention is to provide a vacuum or dust collector including a manually operated device for selectively securing or anchoring or positioning the dust collecting receptacle to the dust collector.
In accordance with one aspect of the invention, there is provided a dust collector comprising a base including a post extended upwardly therefrom, a housing disposed on the post, a dust collecting receptacle, a cover coupled to the housing and disposed above the dust collecting receptacle for selectively closing the dust collecting receptacle or for selectively opening the dust collecting receptacle, and an actuating device for selectively actuating the cover to close the dust collecting receptacle, and for selectively moving and disengaging the cover away from the dust collecting receptacle to open the dust collecting receptacle and to allow the dust collecting receptacle to be moved either away from or toward the base.
The actuating device includes a bar attached to the cover and moved in concert with the cover, and device for moving the bar and the cover to close the dust collecting receptacle. The moving device includes a handle pivotally attached to the post and coupled to the bar for selectively moving the bar and the cover to close the dust collecting receptacle.
The moving device includes at least one arm and a link pivotally coupled between the bar and the handle for allowing the bar and the cover to be moved to close the dust collecting receptacle with the handle.
The handle includes at least one catch extended therefrom for selectively engaging with the arm and for selectively anchoring and positioning the arm and the handle to the plate and the post. The arm may further include a curved portion for engaging with the catch.
The actuating device includes a plate secured to the post, and the handle is pivotally attached to the post with the plate. The plate includes two flaps secured to the plate for forming a space between the flaps, and the handle is pivotally attached to the flaps with a pivot axle.
The housing includes a duct extended from the housing and coupled to the cover with a flexible member. The flexible member is preferably a bellows-type flexible member.
The dust collecting receptacle includes at least one orifice formed therein and coupled to the duct with a pipe, and a dust bag disposed in the dust collecting receptacle. The dust collecting receptacle includes a casing attached to the dust collecting receptacle and having the orifice formed and located within the casing and having an aperture formed in the casing and coupled to the duct with the pipe.
The pipe is coupled to the casing with a flexible member. The flexible member is also preferably a bellows-type flexible member. The pipe includes a control valve for selectively opening and closing the pipe.
The base includes an opening formed therein for slidably receiving the dust collecting receptacle. The base includes at least one rail, and the dust collecting receptacle includes at least one anchor for slidably engaging with the rail of the base and for guiding the dust collecting receptacle to slide and to move relative to the base.
The housing includes a compartment formed in the housing, and a fan device disposed in the compartment of the housing for vacuuming purposes. The housing includes a canister coupled to the housing and communicating with the compartment of the housing for receiving a light weight dust.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
The vacuum collector 1 further includes a housing 20 disposed on top of the post 11 and having a compartment 21 formed in the housing 20 (
For example, an electric vacuum motor or pump 26 is disposed or attached to the upper portion of the housing 20 and coupled to the fan device 25 for rotating or driving the fan device 25 to vacuum or to draw the dust or dirt or fume into the compartment 21 of the housing 20. For example, the housing 20 includes a hose 27 (
Another motor or motor driving device 29 may further be provided and attached or disposed on the housing 20, and preferably arranged or disposed above the filter canister 28, and coupled to a stirring or sweeping or dust removing device (not shown) which is disposed in the filter canister 28 and a filter member that is also disposed in the filter canister 28, for sweeping the dust or the dirt from the filter member and for allowing the dust or the dirt to be easily removed from the filter member and/or to be easily collected within the filter member, in which the dust removing device is not related to the present invention and will not be described in further details, and the dust removing device has been filed and claimed in the other co-pending US patent applications which may be taken as references for the present invention.
A manually operated pressing or actuating means or device 4 is further provided and coupled to the cover 24 for selectively moving or actuating the cover 24 to close the dust collecting receptacle 30 (
It is preferable, but not necessarily that the handle 43 includes a bent portion 45 for allowing the handle 43 to be easily operated or rotated relative to the plate 40 or the flaps 41 by the users. One or more (such as two) arms 46 include an upper portion rotatably or pivotally attached or secured to the middle portion of the handle 43 and spaced from the pivot axle 44 for allowing the arms 46 to be moved up and down relative to the plate 40 or the post 11 with the handle 43 by the users. A link 50 is pivotally attached or secured to the lower portion of the arms 46, and a pressing bar 51 is attached or secured to the cover 24 and moved in concert with the cover 24 and pivotally attached or secured to the lower portion of the link 50 for allowing the cover 24 and the bar 51 and the link 50 to be moved up and down relative to the plate 40 or the post 11 with the handle 43 by the users. The handle 43 and the arms 46 and the link 50 may be formed and acted as a moving means for moving the cover 24 to close the dust collecting receptacle 30.
It is further preferable that the arms 46 each include a bent or curved middle portion 48, and the handle 43 includes one or more (such as two) projections or catches 49 extended laterally and outwardly therefrom (
