Water filter description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] This invention relates to a dust collector, and more particularly,
to a dust collector with an inbuilt cyclonic water filter.
[0003] 2. Background of the Invention
[0004] A conventional dust collector usually filtrates dust with
a cotton filter bag. Dust and air are sucked in the cotton bag,
wherein larger dusts are left in the dust collect box, tiny dusts
and air are discharged by the fan and returned indoors. Thus, it
is easy to cause secondary pollution, and dust will enter into human
lungs easily, doing harm to human health. When dust is dumped, it
flies everywhere, and becomes new pollution sources.
SUMMARY OF THE INVENTION
[0005] The main object of the present invention is to provide a
dust collector with an inbuilt cyclonic water filter, so as to absorb
dust and purify the air.
[0006] The dust collector according to the present invention comprises
a dust collecting unit, a water filter and a fan. Said dust collector
further comprises an incoming air passage and an outgoing air passage.
The outlet of said incoming air passage is connected to the inlet
of said water filter, the outlet of said water filter opens into
the inlet of said outgoing air passage, said incoming and outgoing
air passages are separate from each other.
[0007] With a water filter inbuilt, the dust-containing air enters
the dust collecting unit via the incoming air passage at a tangent.
The air flow in the dust collecting unit is whirled downwards into
the water of the water filter. The dust-containing air is sucked
into the water by negative pressure, generates air bubbles and is
mixed with water. The dust contained in the air is wet and left
in the water, while the purified air is discharged out of the dust
collector. After working with the dust collector, the dust can be
cleared by throwing the dirty water inside the water filter. The
dust collector of the present invention has good working effect.
Besides, the air discharged is clean, no pollution is caused, which
will be good for environment protection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] As shown in FIG. 1 the dust collector of the present invention
comprises a dust collecting unit 1 a water filter 2 and a fan 3.
Inside the dust collector, the outlet 101 of the incoming air passage
10 is connected to the inlet 20 of the water filter 2 the outlet
21 of the water filter 2 is connected to the inlet 111 of the outgoing
air passage 11 said incoming air passage 10 and outgoing air passage
11 are separate from each other.
[0012] As shown in FIG. 2 and FIG. 3 the dust collecting unit
1 is a cup-shaped unit with a cylindrical body installed centrally.
The cavity between the outer shell of said cup-shaped unit and the
outer wall of said cylindrical body constructs the incoming air
passage 10 of said dust collecting unit 1. The inner cavity of said
cylindrical body constructs the outgoing air passage 11 of said
dust collecting unit 1. The inlet 100 of the incoming air passage
10 is installed on the outer wall of said cup-shaped unit, and is
connected to the dust passage 4 of the dust collector. The outlet
101 of the incoming air passage 10 is connected to the inlet 20
of the water filter 2 the outlet 21 of the water filter 2 opens
into the inlet 111 of the outgoing air passage 11 the outlet 112
of the outgoing air passage 11 is separated from the incoming air
passage 10 protrudes from the outer wall of the cup-shaped unit
and is connected to the air flow passage 5 of the dust collector.
[0013] The bottom of the dust collecting unit 1 is in the shape
of a tilted and curved surface, at the bottom tip of which, the
outlet 101 of the incoming air passage 10 enters into the water
of the filter bowl 23 via the inlet 20 of the water filter 2.
[0014] The dust collecting unit 1 may alternately be formed by
connecting the cup body 13 and the upper lid 12 via screw, with
rubber gasket 15 sealed in between. The cup body 13 is matched with
the upper lid 12 which makes the outgoing air passage 11 at the
central position of the cup-shaped unit.
[0015] The water filter 2 comprises a breakwater 22 and a filter
bowl 23. The breakwater 22 and the filter bowl 23 are matched with
each other. A cut opening is made at one side of the breakwater
22 which is the inlet 20 of the water filter. At the other side
of the breakwater 22 through holes are made, which are the outlets
21 of the water filter.
[0016] The filter bowl 23 is in the shape of a semi-sphere.
[0017] The filter net of the breakwater 22 is secured to the plastic
part by over-molding. The whole breakwater 22 is positioned with
the aim of the bottom part of the cylindrical cup body 13 and the
four pieces of reinforces of the filter bowl 23. The central part
of the breakwater 22 is in the shaped of a ringent trump, so as
to block the writhing water sprays effectively. The air returned
enters the top space of the cup body 13 via the outlet 21 at the
brim of the breakwater 22.
[0018] The dust-containing air enters the transparent semi-sphere
cup body 13 via the inlet at a tangent, and generates high speed
turbulence. Since the air flow is of very high speed, static electricity
generates due to the friction between the air flow and the inner
wall. Thereby, some tiny dusts are absorbed and left on the inner
wall of the cup body. Large dusts change from large particles to
small ones along the curved surface, enter the water of the filter
bowl 23 by high speed air flow. Thus, bubbles and sprays arise,
dusts and water are mixed. Because of the function of inertia, large
dusts deposit to the bottom of the water along the curved surface.
Small dusts writhe along with the bubbles, hit the surface of the
trump-shaped breakwater 22 and return to the water, and thus dilute
more thoroughly. The few dusts taken to the filter net of the breakwater
22 by bubbles are broken by the small filter holes, thus, the contact
area between the dust-containing air and the water is increased.
The purified air enters the space constructed by the breakwater
22 and the tilted surface of the cup body 13 passes the outlet
of the cup body 13 and that of the upper lid 12 via the filter net,
and finally is discharged and returned indoors through the fan. |
