Water filter description
BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to a dust collector, and more particularly,
to a dust collector with an inbuilt cyclonic water filter.
2. Background of the Invention
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
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.
The dust collector according to the present invention comprises:
a cup-shaped dust collecting unit having an outer shell and a cylindrical
body installed centrally within said cup-shaped dust collecting
unit, wherein said cylindrical body having an outer wall and an
inner cavity;
a water filter comprising a breakwater and a filter bowl; wherein
said breakwater and the filter bowl are matched with each other,
a cut opening is made at one side of the breakwater, which forms
the inlet of the water filter, at the other side of the breakwater,
through holes are made, which form the outlets of the water filter;
a fan;
a dust passage;
an air flow passage;
an incoming air passage formed between the outer shell of said
cup-shaped dust collecting unit and the outer wall of said cylindrical
body; said incoming air passage has an inlet and an outlet, wherein
said inlet is installed on the outer wall of said cup-shaped dust
collecting unit and is connected to the dust passage of said dust
collector, said outlet opens into the inlet of the water filter;
an outgoing air passage formed in the inner cavity of said cylindrical
body;
wherein, the outlets of the water filter open into the inlet of
the outgoing air passage, the outlet of the outgoing air passage
is separated from the incoming air passage, passes through the outer
wall of the cup-shaped dust collecting unit and is connected to
the air flow passage of the dust collector.
With a water filter inbuilt, the dust-containing air enters the
cup-shaped dust collecting unit via the incoming air passage at
a tangent. The air flow in the cup-shaped 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
As shown in FIG. 1 and FIG. 2 the dust collector of the present
invention comprises a cup-shaped 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 of the outgoing air passage 11 said incoming air passage
10 and outgoing air passage 11 are separate from each other.
As shown in FIG. 2 and FIG. 3 the cup-shaped dust collecting unit
1 has a cylindrical body installed centrally. The cavity between
the outer shell of said cup-shaped dust collecting unit 1 and the
outer wall of said cylindrical body constructs the incoming air
passage 10 of said cup-shaped dust collecting unit 1. The inner
cavity of said cylindrical body constructs the outgoing air passage
11 of said cup-shaped dust collecting unit 1. The inlet 100 of the
incoming air passage 10 is installed on the outer wall of said cup-shaped
dust collecting 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 of the outgoing air passage
11 the outlet 112 of the outgoing air passage 11 is separated from
the incoming air passage 10 passes through the outer wall of the
cup-shaped dust collecting unit and is connected to the air flow
passage 5 of the dust collector.
The bottom of the cup-shaped 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.
The cup-shaped dust collecting unit 1 may comprise a cup body 13
and a upper lid 12 and 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 thereby
the outgoing air passage 11 is formed centrally within the cup-shaped
dust collecting unit.
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
forms the inlet 20 of the water filter. At the other side of the
breakwater 22 through holes are made, which form the outlets 21
of the water filter 2.
The filter bowl 23 is in the shape of a semi-sphere.
The breakwater 22 comprises filter nets, a central member and a
plastic frame. The filter nets of the breakwater 22 are secured
to the plastic frame by means of over-molding. The filter bowl 23
has four reinforcement ribs. The breakwater 22 is positioned with
the aid of the cylindrical body of the cup-shaped dust collecting
unit 1 and the four reinforcement ribs of the filter bowl 23. The
central member of the breakwater 22 is in the shape 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 outlets
21 at the brim of the breakwater 22.
The dust-containing air enters the transparent cylindrical cup
body 13 via the inlet 100 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 through the
filter nets and outlets 21 enters the outgoing air passage 11 located
centrally within the cup body 13 and the upper lid 12 passes through
the fan 3 and finally is discharged and returned indoors. |
