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.
[0032] 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 (FIGS. 1, 3, 6, 8), or for selectively moving or
disengaging the cover 24 away from the dust collecting receptacle
30 to open the dust collecting receptacle 30 (FIGS. 2, 4, 7). For
example, the actuating means or device 4 includes a bracket or
plate 40 attached or disposed or secured to the post 11 with one or
more fasteners 80, one or more (such as two) flaps 41 extended from
the plate 40 or secured to the plate 40 with the fasteners 80 and
preferably arranged parallel to each other for forming a space 42
between the flaps 41. Am actuating arm or handle 43 has one end
pivotally attached or secured to the post 11 or the plate 40 or the
flaps 41 with a pivot axle 44 for allowing the handle 43 to be
rotated relative to the plate 40 or the flaps 41.
[0033] 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

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.
[0034] 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 (FIGS. 6-8) for selectively engaging with the
bent or curved middle portions 48 of the arms 46 and for
selectively anchoring or positioning the arms 46 and the handle 43
to the plate 40 and the post 11 (FIGS. 6 and 8) and for securing or
positioning or retaining the cover 24 in engagement with the dust
collecting receptacle 30 or in closing the dust collecting
receptacle 30. The catches 49 may be forced to move over the bent
or curved middle portions 48 of the arms 46 with the handle 43 and
to selectively open the dust collecting receptacle 30 when it is
required to clean or dump the dust collecting receptacle 30 or when
it is required to disengage the dust from the dust collecting
receptacle 30. The dust collecting receptacle 30 may include two or
more wheels 32 for moving the dust collecting receptacle 30 away
from or toward the base 10.
[0035] In operation, as shown in FIGS. 1, 3, 6, 8, when the dust
collecting receptacle 30 has been moved into the opening 15 of the
base 10, the cover 24 may be moved and forced downwardly to engage
with and to cover or seal the dust collecting receptacle 30 the
handle 43, and thus to stably position or to retain the dust
collecting receptacle 30 to the base 10 and to prevent the dust
collecting receptacle 30 from being disengaged or moved away from
the base 10. On the contrary, when it is required to clean or dump
the dust collecting receptacle 30 or when it is required to
disengage the dust from the dust collecting receptacle 30, the
handle 43 may move the cover 24 and the bar 51 and the link 50 up
relative to the plate 40 or the post 11 to disengage the cover 24
from the dust collecting receptacle 30 and to open the dust
collecting receptacle 30 (FIGS. 2, 4, 7).
[0036] As shown in FIGS. 3 and 4, the dust collecting receptacle 30
may further include a dust bag 33 selectively engageable into the
dust collecting receptacle 30, and includes one or more orifices 34
formed in the outer peripheral portion of the dust collecting
receptacle 30 and preferably disposed or located in the lower
portion of the dust collecting receptacle 30, and includes a casing
35 attached or secured to the dust collecting receptacle 30 and
having the orifices 34 formed and located within the casing 35 and
having an aperture 36 formed and provided in the casing 35, and
includes a manifold or pipe 37 coupled to the duct 22 and coupled
to the aperture 36 of the casing 35 with another a bellows-type
flexible or foldable or extendible member 38 for allowing the dust
collecting receptacle 30 to be disengaged or moved away from the
base 10 as shown in dotted lines in FIG. 4. A control valve 39 may
be provided and attached or coupled to the pipe 37 for selectively
opening or closing the pipe 37.
[0037] In operation, as shown in FIG. 3, when a dust bag 33 is
selectively engaged into the dust collecting receptacle 30 and when
the control valve 39 or the pipe 37 is opened, the fan device 25
may partially draw the air through the pipe 37 in order to vacuum
or to draw the dust bag 33 toward or against the inner peripheral
portion of the dust collecting receptacle 30 and thus for allowing
the dust bag 33 to suitably collect the dust or the dirt. When no
dust bag 33 is engaged into the dust collecting receptacle 30, the
control valve 39 or the pipe 37 should be closed for preventing the
dust or the dirt in the dust collecting receptacle 30 from being
drawing into the pipe 37.
[0038] Accordingly, the vacuum collector in accordance with the
present invention includes 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 collected within the dust collecting receptacle to be
easily and quickly cleaned or dumped from the dust collecting
receptacle, and includes a manually operated device for selectively
securing or anchoring or positioning the dust collecting receptacle
to the dust collector.
[0039] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
