[0017] FIG. 5 is an illustrative view of the dust collector in accordance with the present invention showing the collector is under clean maintenance to recollect the particulate dust; and

[0018] FIG. 6 is an illustrative view of a second embodiment of the dust collector in accordance with the present invention showing a dust collection bag is contained in the dust collection barrel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] Referring to FIG. 2 and FIG. 3 which are a perspective view of a dust collector in accordance with the present invention and a partially sectional view of the dust collector illustrating the same being in use for dust collection, a dust collector 100 comprises a collector body 10, a dust collection tube 20 telescopic shaped, a dust collection barrel 30 equipped under the dust collection tube 20.

[0020] A filter barrel 40 installed in the collector body 10 comprises a filter net 41 to filter the air mixed with dust and a dust clean device 42 installed in the filter barrel 40 which is operated by a handle 43 extended outward the filter barrel 40 and the collector body 10. There is an air outlet adaptor 44 formed at the lower portion of the filter barrel 40. The air outlet adaptor 44 is communicating with the inner portion of the filter net 41 of the filter barrel 40 and is also communicating with the dust collection tube 20. If the particulate dust contained in the driven air and filtered to stick on the filter net 41 reached a preset volume, the dust collector may automatically stop.

[0021] An air suction unit 50 is equipped in the collector body 10 to guide the environmental air into the collector body 10 through the dust collection tube 20. The air will be in turn driven to pass through the dust collection barrel 30 as well as the filter net 41 of the filter barrel 40. Filtered clean air will be released out of the collector body 10. It is readily to know that the air suction unit 50 can be an air pump or an electric fan.

[0022] A cover 60 can be fitted onto the air outlet adaptor 44 to either close or open the same.

[0023] A dust detection unit 70 comprises a dust detection device 71 which is installed in the collector body 10 and an alarm device 72. The function of the dust detection unit 70 is to detect the particulate dust volume filtered and contained on the filter net 41 d and in the dust collection barrel 30. It is readily to know that the dust detection device 71 can be a pressure sensor and the alarm device 72 can be a LED.

[0024] When the dust collector 100 in accordance to the present invention is actuated to function the particulate dust collection, please still refer to FIGS. 2 and 3. The cover 60 shut the air outlet adaptor 44 of the filter barrel 40. The environmental air will be driven into the collector body 10 through dust collection tube 20. The heavier particulate dust will drop and stored in the dust collection barrel 30. Relatively cleaned air will then be filtered by the filter net 41 of the filter barrel 40 and release to the outside of the collector body 10. During the operation of dust collection, the detection device 71 and alarm device 72 will keep on monitoring the dust volume on the filter net 41 and in the dust collection barrel 30 to make sure an effective operation of the dust collection.

[0025] Referring to FIGS. 4 and 5 which are illustrative views of the dust collector in accordance with the present invention showing the dust collection tube being connected to the air outlet adaptor and under clean maintenance to recollect the particulate dust, it is understood the cover 60 will be fixed onto the air outlet adaptor 44 so that the dust collector 100 will operate its dust collection function. The particulate dust will either be dropped in the dust collection barrel 30 or trapped by the filter net 41 of the filter barrel 40.

[0026] When the particulate dust has been accumulated on the filter net 41 more than a preset volume, the dust collector 100 needs to operate its clean maintenance process. The cover 60 will be uncovered from the air outlet adaptor 44 and one end of the dust collection tube 20 will be fixed onto the air outlet adaptor 44. By rotating the handle 43, dust clean device 42 will be actuated to sweep and clean the filter net 41 causing the particulate dust to drop in the filter barrel 40 and then sucked into the dust collection barrel 30 through the dust collection tube 20. The filter net 41 and the filter barrel will be cleaned without a secondary pollution during the clean maintenance.

[0027] Referring to FIG. 6 which is an illustrative view of a second embodiment of the dust collector in accordance with the present invention, a dust collection bag 80 is equipped in the dust collection barrel 30. The dust collection bag 80 can be removed and littered from the dust collector 100 when the particulate dust has been collected almost full in the dust collection bag 80. The alarm device 72 serves the function to remind the user to conduct the clean maintenance. By this way, there will be no secondary pollution.

[0028] Although the dust collector capable of recollecting particulate dust in the filtered barrel in accordance with the present invention has been described by way of preferred embodiment, it will become apparent and easily understood that changes, improvement and modifications may still be possible but without departing from the spirit of the current invention and still fallen in the protection scope as the claims of the invention.
