Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a dust collector, and more
particularly, to a water filtered dust collector.
[0003] 2. Description of Related Arts
[0004] An ordinary dust collector has a dust chamber or is equipped
with an extra dust bag based on the dust chamber. As each type of
dust collector has a different model, many factors such as the
shape and the operation method of each dust collector should be
considered when manufacturing the corresponding dust chamber. Also,
in general, the dust chamber can be used only once, or it should be
cleaned after being used for several times. But after being used
for a too long time, more and more dust hard to be cleaned will
accumulate. And therefore, the reusability of the dust chamber is
affected, the use-cost of the product is increased and it is not
environmentally friendly. And for the dust collector with a dust
bag, the material of the dust bag may generally allow both air and
dust pass through. The dust collector is used to clean the dust in
the room, but the dust will suspend in the air through the dust bag
of the dust collector. Also, the material of such a dust bag is
generally soft, and therefore, some special material is needed to
connect and fix with the dust inlet port of the dust collector,
which is inconvenient for the users replacing the dust bag.
Furthermore, such dust bag can be used only once, so it's not
environmentally friendly.
SUMMARY OF THE PRESENT INVENTION
[0005] The object of the present invention is to overcome the
drawbacks of prior art, and to provide a water filtered dust
collector, which can be recycled, easy to clean and can satisfy the
requirements for environmental protection.
[0006] To realize the above technical solution, the present
invention adopts the following technical solution:
[0007] Such a water filtered dust collector comprises a housing
with a handle that is consisted of front and back housings, which
are engaged with each other. A battery package is disposed at one

DETAILED DESCRIPTION OF THE INVENTION
[0026] The present invention is further described with referent to
the accompanying drawings as follows.
[0027] As shown in FIGS. 1 to 4, the water filtered dust collector
comprises a housing 1 with a handle that is consisted of front and
back housings 12,14, which are engaged with each other. A battery
package 2 is disposed at one end of the housing, and a suction
nozzle 3 is disposed at the other end. A suction nozzle mounting 32
communicating with the suction nozzle is disposed at the bottom of
the suction nozzle. A suction nozzle fixing bush 4 is disposed
between the suction nozzle mounting and the housing to connect and
fix them. An electric motor 5 driven by the batteries in the
battery package and fan blades 6 driven by the electric motor are
disposed in the suction nozzle fixing bush and the housing. A water
vessel 7 for holding water is disposed in parallel to the suction
nozzle on the suction nozzle mounting. An air steering pipe 42,
which can redirect the water-filtered air, is disposed at a
position corresponding to the suction nozzle on an end surface far
from the suction nozzle of the suction nozzle mounting. An air
inlet pipe 44 is disposed on the septum of the suction nozzle
fixing bush, with one end inserted into the water vessel to
communicate the suction nozzle fixing bush with the water vessel.
The air steering pipe 42 extends in a direction opposite to the
direction the air inlet pipe 44 extends in the suction nozzle
fixing bush 4 to form a cavity 46, which corresponds to the center
of the fan blades 6. The air inlet pipe 44 is a straight pipe with
an elbow 48 of 90 degrees at the end of the water vessel 7. The
water vessel 7 connects with the suction nozzle mounting 32, and a
boss 322 is disposed on the suction nozzle mounting, on which the
water vessel can be enclosed removably. The air inlet pipe 44
extends through the suction nozzle mounting and is located at the
center of the water vessel, and the connection between the suction
nozzle mounting and the air inlet pipe is a tight connection. The
battery package 2 and the housing 1 are fixed and connected by a
connection plug 8. The connection plug 8 has a body 82, with two
elastic clip pins 84 at one end of the body, wherein the width of
the two ends of the body is greater than that of the clip pins, and
the two ends are disposed within the clip socket 16 at a
corresponding position of the housing 1. A handheld handle 18 is
formed after engaging the front and back housings 12,14. And an
exhaust slot 9, which may exhaust the air from the air steering
pipe 42 out of the dust collector, is disposed at the position
opposite to the handle. The water vessel 7 may be cylindrical.
Screws 10 are used to fix them in many places when assembling the
front and back housings.
[0028] When assembling, fill the water vessel 7 with water at
first, with the sucker downwards, and the water surface in the
water vessel lower than the opening of the air inlet pipe. Then
enclose it on the boss 322 on the suction nozzle mounting 32 of the
dust collector. Thus a layer of special water-solidifiable glue is
disposed previously between them such that an airproof effect may
be achieved after they are connected. When being used, a control
switch 9 is turned on first to communicate the electric motor 5
with the batteries in the battery package 2, such that driven by
the electric motor, the fan blades 6 begin rotating and a suction
is generated, drawing out all the air in the suction nozzle fixing
bush 4, the suction nozzle mounting 32 and the dust collector to
form a vacuum state. Thus a strong suction is generated at the
sucker 34 of the suction nozzle 3. And therefore, when the sucker
contacts the object surface to be cleaned, the dust is sucked in by
the strong suction via the sucker, moves towards the suction nozzle
mounting 32 along the suction nozzle, and then enters the water
vessel 7 filled with water along the air inlet pipe 44. Because an
air inlet pipe with an elbow 48 of 90 degrees is disposed at the
end of the air inlet pipe 44, water in the water vessel will not
flow back into the suction nozzle fixing bush. After entering the
water pipe, the air with dust contacts the water surface, and will
suspend in the water, instead of adhering to the pipe wall after
being filtered by water. So the air is without dust when entering
the air steering pipe 42. Subsequently the clean air is exhausted
out of the dust collector via the exhaust slot 9. Finally the water
vessel can be disassembled to replace the water, and then enclosed
on the suction nozzle mounting for reuse.
[0029] As described above, compared with prior art, the water
filtered dust collector has the following advantages: easy for
cleaning, as it is filtered by water; easy for replacing, as it is
convenient to assemble and disassemble the device collecting dust;
environmentally friendly, as the water vessel used for collecting
dust and filtering can be reused; and reducing the use-cost, as the
water vessel can be made into various shapes and thus has a high
applicability.
